+	component of a "memory exhausted" message in slot 0.
+	From a suggestion by Jim Meyering.
+
+2000-07-30  Jim Meyering  <meyering@lucent.com>
+
+	* makepath.c (make_path): Quote the other instance, too.
+
+	* quotearg.c (N_STATIC_SLOTVECS): Define.
+	(STATIC_BUF_SIZE): Define.
+	(quotearg_n_options): Use only statically allocated storage when
+	N < N_STATIC_SLOTVECS and the length of the quoted result is smaller
+	than STATIC_BUF_SIZE.
+
+2000-07-29  Jim Meyering  <meyering@lucent.com>
+
+	* diacrit.c (diacrit_diac): Use __MSDOS__ in favor of MSDOS.
+	* dirname.c (dir_name): Likewise.
+
+	* basename.c (base_name): Use ISSLASH rather than comparing against `/'.
+
+	* dirname.c (dir_name) [MSDOS]: Declare `lim' to be const.
+	(dir_name): Assert that there are no trailing slashes.
+
+2000-07-18  Bruno Haible  <haible@clisp.cons.org>
+
+	* mbswidth.h (mbswidth): Add a flags argument.
+	(mbswidth): New declaration.
+	(MBSW_ACCEPT_INVALID, MBSW_ACCEPT_UNPRINTABLE): New macros.
+	* mbswidth.c (mbswidth): Add a flags argument.
+	(mbsnwidth): New function.
+
+2000-07-24  Jim Meyering  <meyering@lucent.com>
+
+	* mbswidth.c: Remove useless #else.  From Bruno Haible.
+
+2000-07-23  Paul Eggert  <eggert@twinsun.com>
+
+	* mbswidth.c (_XOPEN_SOURCE):
+	Don't define; this causes problems on Solaris 7.
+	(wcwidth) [!HAVE_DECL_WCWIDTH]: Declare.
+
+2000-07-23  Paul Eggert  <eggert@twinsun.com>
+
+	* quotearg.c:
+	Include <wchar.h> even if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX),
+	so that mbstate_t is always defined.
+
+	Do not inspect MB_LEN_MAX, since it's incorrectly defined to
+	be 1 in at least one GCC installation, and this configuration
+	error is likely to be common.  Ignoring MB_LEN_MAX hurts
+	performance on hosts that have mbrtowc but have only unibyte
+	locales, but I assume these hosts are rare.
+
+2000-07-23  Paul Eggert  <eggert@twinsun.com>
+
+	* quotearg.c: Streamline by invoking multibyte code only if needed.
+	<wchar.h>: Include only if HAVE_MBRTOWC && 1 < MB_LEN_MAX.
+	(MB_CUR_MAX): Redefine to 1 if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX).
+	(quotearg_buffer_restyled): If a unibyte locale, don't bother to
+	invoke multibyte primitives.
+
+2000-07-23  Jim Meyering  <meyering@lucent.com>
+
+	* basename.c (base_name): Add an assertion.
+
+2000-07-15  Bruno Haible  <clisp.cons.org>
+
+	* quotearg.c: When the system forces us to redefine mbstate_t,
+	shadow its mbsinit function.
+
+2000-07-16  Bruno Haible  <haible@clisp.cons.org>
+
+	* mbswidth.h: New file.
+	* mbswidth.c: New file.
+	* Makefile.am (libfetish_a_SOURCES): Add mbswidth.c.
+	(noinst_HEADERS): Add mbswidth.h.
+
+2000-07-17  Bruno Haible  <haible@clisp.cons.org>
+
+	* config.charset: Add support for FreeBSD. Improve support for HP-UX
+	and IRIX 6.
+
+2000-07-15  Jim Meyering  <meyering@lucent.com>
+
+	* makepath.c: Include quote.h.
+	(make_path): Convert "`%s'" in format strings to "%s", and wrap each
+	corresponding argument in a `quote (...)' call.
+	Give better diagnostics.
+
+	* Makefile.am (libfetish_a_SOURCES): Add quote.c.
+	(noinst_HEADERS): Add quote.h.
+
+	* quote.c (quote, quote_n): New file.  Two functions taken verbatim
+	from tar's src/misc.c.
+	* quote.h: New file.  Prototypes for same.
+
+2000-07-10  Paul Eggert  <eggert@twinsun.com>
+
+	From a suggestion by Bruno Haible.
+	* quotearg.c (mbrtowc): Do not use HAVE_WCHAR_H in the definition.
+	Use defined mbstate_t, not HAVE_MBSTATE_T_OBJECT,
+	to decide whether to define the BeOS workaround macro;
+	this adjusts to the change to AC_MBSTATE_T.
+
+2000-07-13  Paul Eggert  <eggert@twinsun.com>
+
+	* quotearg.h (enum quoting style): New enum clocale_quoting_style.
+
+	* quotearg.c: (quoting_style_args, quoting_style_vals,
+	quotearg_buffer_restyled): Add support for
+	clocale_quoting_style.  Undo previous change to
+	locale_quoting_style behavior, and undo the "{LEFT QUOTATION MARK}"
+	and "{RIGHT QUOTATION MARK}" msgids.
+
+2000-07-05  Paul Eggert  <eggert@twinsun.com>
+
+	The old behavior of quoting `like this' doesn't look good with
+	newer, ISO-style fonts.  See:
+	http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html
+
+	Instead, quote "like this" by default.  Let the translator
+	tailor the locale-specific quoting behavior by providing
+	translations for {LEFT QUOTATION MARK} and {RIGHT QUOTATION MARK}.
+
+	* quotearg.c (N_): New macro.
+	(gettext_default): New function.
+	(quotearg_buffer_restyled): Use
+	gettext_default ("{LEFT QUOTATION MARK}", "\"") for left quote, and
+	gettext_default ("{RIGHT QUOTATION MARK}", "\"") for right quote.
+
+2000-07-09  Jim Meyering  <meyering@lucent.com>
+
+	* Most files: Update copyright dates to include 2000.
+
+2000-07-08  Jim Meyering  <meyering@lucent.com>
+
+	* xgethostname.c (ENAMETOOLONG): Define to an unlikely value
+	if not defined.
+	(xgethostname): Remove now-unnecessary #ifdef.
+	Move declaration of `err' into loop where it's used.
+
+2000-07-05  Bruno Haible  <haible@clisp.cons.org>
+
+	* xgethostname.c (xgethostname): Protect against the SunOS5.5 bug
+	by allocating a larger buffer. Test the gethostname return value for
+	being >= 0, not == 0, for BeOS.  Don't exhaust memory if gethostname
+	returns an error and ENAMETOOLONG isn't defined.
+
+2000-07-05  Paul Eggert  <eggert@twinsun.com>
+	and Bruno Haible  <haible@clisp.cons.org>
+
+	* quotearg.c (mbrtowc): Declare returned type, since BeOS doesn't.
+
+2000-07-05  Bruno Haible  <haible@clisp.cons.org>
+
+	* quotearg.c (struct quoting_options): Simplify quote_these_too
+	dimension.
+
+2000-07-03  Jim Meyering  <meyering@lucent.com>
+
+	* strndup.c: [!HAVE_DECL_STRNLEN]: Declare strnlen.
+	Reported by Bruno Haible.
+
+2000-07-04  Jim Meyering  <meyering@lucent.com>
+
+	* quotearg.c: Make inclusion of <wchar.h> independent of whether
+	HAVE_MBRTOWC is set.  Required at least for irix-5.6, which
+	lacks mbrtowc.
+
+2000-07-03  Paul Eggert  <eggert@twinsun.com>
+	and Bruno Haible  <haible@clisp.cons.org>
+
+	* quotearg.c (mbrtowc):
+	Assign to *pwc, and return 1 only if result is nonzero.
+	(iswprint): Use ISPRINT when substituting our own mbrtowc.
+
+2000-07-03  Jim Meyering  <meyering@lucent.com>
+
+	* readutmp.h: [HAVE_UTMPX_H]: Include <utmp.h> if HAVE_UTMP_H.
+	This is necessary to get a definition of e.g., UTMP_FILE on HP-UX 10.20.
+	From Bob Proulx.
+
+2000-07-02  Jim Meyering  <meyering@lucent.com>
+
+	* quotearg.c (mbstate_t): Don't define here.
+
+2000-07-02  Jim Meyering  <meyering@lucent.com>
+
+	* nanosleep.c (SIGCONT): Define if not already defined.
+
 2000-06-17  Bruno Haible  <haible@clisp.cons.org>
 
 	* mountlist.c: Use MOUNTED_FS_STAT_DEV instead of MOUNTED_NEXT_DEV,

+	 Suppose there is a byte with all zeros.  Any carry bits
+	 propagating from its left will fall into the hole at its
+	 least significant bit and stop.  Since there will be no
+	 carry from its most significant bit, the LSB of the
+	 byte to the left will be unchanged, and the zero will be
+	 detected.
+
+	 2) Is this worthwhile?  Will it ignore everything except
+	 zero bytes?  Suppose every byte of LONGWORD has a bit set
+	 somewhere.  There will be a carry into bit 8.  If bit 8
+	 is set, this will carry into bit 16.  If bit 8 is clear,
+	 one of bits 9-15 must be set, so there will be a carry
+	 into bit 16.  Similarly, there will be a carry into bit
+	 24.  If one of bits 24-30 is set, there will be a carry
+	 into bit 31, so all of the hole bits will be changed.
+
+	 The one misfire occurs when bits 24-30 are clear and bit
+	 31 is set; in this case, the hole at bit 31 is not
+	 changed.  If we had access to the processor carry flag,
+	 we could close this loophole by putting the fourth hole
+	 at bit 32!
+
+	 So it ignores everything except 128's, when they're aligned
+	 properly.
+
+	 3) But wait!  Aren't we looking for C, not zero?

+2000-11-05  Jim Meyering  <meyering@lucent.com>
+
+	* Version 4.0.31.
+
+	* configure, config.h.in, Makefile.in, etc.: Regenerate using the
+	very latest version (in CVS) of autoconf.
+
+	* src/mkdir.c (main): Use make_dir instead of using mkdir directly.
+	Diagnose as failure when mkdir tries to create (without the
+	--parent (-p) option) a directory that already exists.
+	* tests/cp/cp-parents: Add a test for the above fix.
+
+	* tests/mv/mv-special-1: Clean up this test.
+
+2000-11-01  Jim Meyering  <meyering@lucent.com>
+
+	* Version 4.0.30.
+
+	* src/chmod.c (main): Better diagnostics.
+
+2000-10-31  Jim Meyering  <meyering@lucent.com>
+
+	* tests/lang-default: Add all the internationalization-related
+	variable names autoconf uses.  Set and export them in a loop.
+
+	`mkdir -p' would create parent directories with permissions
+	that did not account for the umask. [introduced with the
+	2000-09-30 change that became part of fileutils-4.0.28]
+	* src/mkdir.c: Include dirname.h.
+	Compute the parent directory `mode' unconditionally, effectively
+	as `$(umask -S),u+wx'.
+	Use make_path to create only the parent directories, thus using
+	the same code, both with and without -p, to create the final
+	component in each file name.  Reported by Bob Proulx.
+
+	Add tests for the above fix.
+	* tests/cp/cp-parents: Add some permission tests.
+	* tests/mkdir/perm: Fix the test so it actually does something.
+	Run each test also with mkdir's `-p' option and check permissions
+	on the parent directories.
+
+2000-10-23  Paul Eggert  <eggert@twinsun.com>
+
+	* doc/getdate.texi: Use @sc where appropriate.  Document the
+	ranges of supported times more precisely.  Correct menu
+	spacing.  Document old Latin 12m/12pm tradition.  Remove list
+	of alphabetic time zone names, as it wasn't correct and people
+	shouldn't be relying on it anyway.  Relative items also
+	account for non-DST adjustments.  Fix some misspellings.
+
+2000-10-30  Jim Meyering  <meyering@lucent.com>
+
+	* configure, config.h.in, Makefile.in, etc.: Regenerate using the
+	very latest version (in CVS) of autoconf.
+
+2000-10-29  Jim Meyering  <meyering@lucent.com>
+
+	* Version 4.0.29.
+
+	* src/cp.c (do_copy): When constructing dst_path for use with the
+	--parents option, first remove any trailing slashes from the command
+	line argument.  Otherwise, tests/cp/cp-parent would fail on NetBSD.
+
+	* tests/cp/cp-parents: Add a test.
+
+	* src/ls.c (DT_INIT): Define.
+	[enum filetype]: Remove the #ifdef, and use DT_INIT on the
+	initializers instead.  `unknown' was undefined for some systems.
+	Reported by John David Anglin.
+
+	* tests/lang-default (LC_COLLATE): Set it to the empty string and
+	export it.  Otherwise, tests/cp/cp-mv-backup would fail e.g., when
+	LC_COLLATE was set to en.  Reported by Vin Shelton.
+
+2000-10-28  Jim Meyering  <meyering@lucent.com>
+
+	* src/ls.c (main): In call to gobble_file with `"."', use `directory'
+	as the type, not `unknown'.
+	[enum filetype] (arg_directory): Rather than `100', use
+	a number that should never conflict with another DT_* value.
+	From Ulrich Drepper.
+
+	* Version 4.0.28.
+
+	Make `ls' a lot more efficient on systems (e.g., linux-2.4.*)
+	that store file type information in directory entries.
+
+	* src/ls.c [enum filetype] (unknown):
+	Add members (as yet unused):
+	(HAVE_STRUCT_DIRENT_D_TYPE): Define.
+	(format_needs_type): New global.
+	(main): Set it.
+	(print_dir): Set `type' from directory entry, if possible.
+	(gobble_file): Add a parameter, TYPE.
+	Stat the file only if its type is unknown and we need the type.
+	Patch from Ulrich Drepper.
+
+	Shred can now determine the size of a block devices (e.g. /dev/fd0)
+	by writing until a write operation fails.
+
+	* src/shred.c: Include assert.h.
+	(fillrand): Add a parameter, size_max.
+	Adjust caller.
+	Add an assertion.
+	(dopass): Break out of the `for (;;)' loop if size < offset.
+	That can happen now that dopass is called with SIZE == -1.
+	(do_wipefd): Accept a length of zero only for a regular file.
+	If lseek fails or returns 0 for a non-regular file, let dopass
+	determine the length.
+	Inspired by a patch from Alan Iwi.
+
+	* tests/Makefile.am (EXTRA_DIST): Add lang-default.
+
+	* tests/rm/hash: Factor out the expensive-test-checking code, ...
+	* tests/expensive: ... into this new file.
+	* tests/cp/perm: Disable this test by default; it's expensive.
+	Mark this as an expensive test.
+	* tests/Makefile.am (EXTRA_DIST): Add expensive.
+
+	* doc/fileutils.texi (shred invocation): Give two examples.

+	(main): Rename local `symbolic_mode' to `specified_mode'.
+
+	* src/mkdir.c (main): Don't set the umask to 0 and hand-apply
+	the previously-set umask unconditionally.  Do that only when a
+	MODE has been specified.  Otherwise, call mkdir with the full
+	creation mask (0777 or 0666) and let the kernel apply the umask.
+	The difference shows up only on file systems with ACL support
+	when the containing directory has a default ACL.
+	Patch by Andreas Gruenbacher.
+	(main): Rename local `symbolic_mode' to `specified_mode'.
+	* src/mknod.c (main): Likewise (but `call mknod', not mkdir).
+	Also, when MODE is specified, call chmod to ensure that the
+	permission bits are set as specified even when the containing
+	directory has a default ACL.
+	Patch by Andreas Gruenbacher.

+2000-08-17  Andreas Gruenbacher  <ag@bestbits.at>
+
+	* src/chmod.c (change_file_mode): Perform the chmod even if the
+	file mode permission bits are the same as those that should be set.
+	Omitting the chmod call would be alright with minimal 1003.1e DS17
+	ACLs, but eventually there may be other permissions in addition to
+	rwx.  E.g., add and delete for directories, and something analogous
+	to NT's take ownership permission.

+
+	* tests/cp/same-file: Don't use `diff -u'.  It's not portable.
+	Reported by Christian Krackowizer.
+	* tests/cp/same-file: Run `diff -c' only if cmp finds a difference.
+	* tests/mv/part-symlink: Likewise.  And clean up.
+
+	`shred --exact file1 file2' wouldn't touch `file1'
+	* src/shred.c (long_opts): --exact doesn't take an argument.
+	Reported by Alan Iwi.
+	* tests/shred/exact: New test for this.
+	* tests/shred/Makefile.am (TESTS): Add exact.
+
+	* Makefile.maint (PREV_VERSION): Get the value from a file, rather
+	than trying to derive it from the current version number.
+	This is much more robust.
+	(alpha): Record just-released version number in `.prev-version',
+	and commit (post-tag).

+
+	* tests/ls/time-1: Output more information when a test fails.
+
+2000-09-22  Jim Meyering  <meyering@lucent.com>
+
+	* src/install.c (cp_option_init): Once again make it so install always
+	unlinks an existing destination before trying to open it for writing.
+	Otherwise, installing onto a running shared library would make the
+	running program malfunction.
+	Reported by Dan Pascu via Michael Stone.
+
+	* src/mv.c (do_move): Moving a directory specified with a trailing
+	slash from one partition to another, and giving it a different
+	name at the destination would cause mv to get a failed assertion.
+	Reported by Michael Stone.
+	(strip_trailing_slashes_2): Move function definition to precede
+	new first use.
+	* tests/mv/part-rename: New test for the above fix.

+
+2000-09-19  Jim Meyering  <meyering@lucent.com>
+
+	* doc/fileutils.texi (cp invocation): Describe how --force works.
+	Update description of -P (soon to change meaning to conform w/POSIX).
+	Describe --remove-destination.
+
+	* src/cp.c (main): When used with --force, each of the --link and
+	--symbolic-link options now implies --remove-destination.
+	Reported by Miles Bader via Mike Stone.
+	* tests/cp/link: New file.  Test for the above fix.
+	* tests/cp/same-file: Adjust for this change in behavior.
+
+2000-09-15  Volker Borchert  <bt@teknon.de>

+
+2000-09-16  Jim Meyering  <meyering@lucent.com>
+
+	* doc/perm.texi (Changing Special Permissions): Remove this statement:
+	``a' in the USERS part of a symbolic mode does not cause the special
+	permissions to be affected'...  It doesn't reflect what the code does
+	and isn't required by POSIX.  Reported by aldomel@ix.netcom.com via

+
+2000-09-09  Jim Meyering  <meyering@lucent.com>
+
+	* Makefile.maint (announcement): Use a stricter regexp for the

+
+	* Version 4.0z.
+
+	* tests/cp/special-bits: New file.
+	* tests/cp/Makefile.am (TESTS): Add special-bits.
+	(TESTS_ENVIRONMENT): Propagate $MAKE into environment, for special-bits.
+
+	* src/copy.c (SAME_OWNER, SAME_GROUP, SAME_OWNER_AND_GROUP): Define.
+	(copy_internal): Avoid calling chown if we know it's not necessary.
+
+	* src/copy.c (copy_internal): Call chmod also if we've made the
+	preceding chown call and we're supposed to preserve some special
+	permission bit(s) that would have been reset by chown.
+	Reported by Greg Louis.
+
+2000-09-08  Jim Meyering  <meyering@lucent.com>
+
+	* src/mkdir.c (S_IRWXUGO): Remove definition.

+
+2000-09-05  Jim Meyering  <meyering@lucent.com>
+
+	* tests/mv/part-symlink: Redirect stdout to stderr before trying to
+	remove the temp directory.  Otherwise, the `rm -rf' would get an
+	error because the output file wouldn't be closed and the directory
+	wouldn't be `empty'.
+	* tests/cp/same-file: Likewise.
+
+	* tests/cp/same-file: Remove the `cp -dl sl1 sl2' case,
+	since it's no longer portable (hard link to a symlink).
+	Likewise for the `cp -bdl symlink foo' case.
+
+	* config.guess: Update from master repository.
+
+2000-09-04  Jim Meyering  <meyering@lucent.com>
+
+	* src/cp.c: Move declaractions of lstat, stat, and rpl_lstat
+	as well as the definition of lstat from here...
+	* src/copy.h: ...to here.
+	* src/copy.c: Remove declaration of lstat, now that it's in copy.h.
+
+	* tests/mv/force: mv's --force (-f) option is no longer needed for
+	this test, now that all it does is cancel --interactive (-i).
+
+	* tests/cp/same-file: Add new tests using cp's --rem option.
+	Reflect the fact that cp's -f option no longer causes cp to remove the
+	destination file before trying to open it.
+	Reflect the fact that `cp -bdl' now makes a backup when copying a
+	symlink onto the file it points to (FIXME: look into this, and why
+	cp -bl does *not* do so).
+
+	* src/ln.c (do_link): Tweak diagnostics.
+
+2000-09-03  Jim Meyering  <meyering@lucent.com>
+
+	* src/install.c (cp_option_init): Initialize new members.
+
+	* src/cp.c (enum): Add UNLINK_DEST_BEFORE_OPENING.
+	[long_options]: Add an entry for --remove-destination.
+	(usage): Describe --remove-destination.
+	(do_copy): Use unlink_dest_after_failed_open member, not `force.'
+	(cp_option_init): Initialize new members.
+	(main): Handle UNLINK_DEST_BEFORE_OPENING (aka --remove-destination).
+
+	* src/mv.c: Remove obsolete comment block.
+	(cp_option_init): Initialize new members.
+	(usage): Reflect the fact that --force (-f) relates only to whether
+	mv prompts.
+	(main): Remove uses of old `force' option member.
+
+	* src/install.c (cp_option_init): Reflect
+
+	`force' no longer means unlink-dest-before-opening
+	* src/copy.h (struct cp_options) [force]: Remove member.
+	[unlink_dest_before_opening]: Add member.  `cp -f' and `mv -f' used to
+	do this.  Now, you must use `cp --remove-destination' to get this
+	behavior.  Now, `cp -f' and `mv -f' work as required by POSIX.
+	[unlink_dest_after_failed_open]: Add member.
+	Paul Eggert reported that `cp -f' removes an existing destination
+	file unconditionally, and that is contrary to POSIX.
+
+	* src/copy.c (same_file_ok): New function, extracted from copy_internal,
+	and rewritten.
+	(copy_internal): Unlink destination file when unlink_dest_before_opening
+	option is set, and when the source is neither a regular file nor a
+	directory.
+
+	* tests/mv/Makefile.am (TESTS): Add part-symlink.
+
+	* src/ls.c: Use strcoll (not strcmp) when comparing file names.
+	Suggestion from Ulrich Drepper.
+
+2000-08-27  Jim Meyering  <meyering@lucent.com>
+
+	* src/copy.c (copy_reg): New parameters: X and NEW_DST.
+	Remove the SPARSE_MODE parameter.  Update caller.
+	Perform POSIX-mandated (for cp) open-with-O_WRONLY|O_TRUNC when copying
+	a regular source file and the destination file exists;  upon failure,
+	unlink that existing file, then open again, but with O_WRONLY|O_CREAT.
+	(copy_internal): `force' in not related to interactive; remove
+	the conjunct.
+	Remove the entire `else if (x->force)' block;  justifying
+	removal of the non-directory part is easy:  POSIX requires we try
+	to open an existing regular file, so we can't unlink it beforehand.
+	The part that changes the mode on a directory to allow overwriting
+	isn't necessary.
+
+	* src/copy.c (copy_reg): Rename two goto labels.
+	(copy_internal): Set `new_dst' when the move_mode rename fails,
+	since we then unlink the destination file.
+
+	* src/cp.c (usage): --force is independent of --interactive.
+
+2000-08-24  Jim Meyering  <meyering@lucent.com>
+
+	Put back the kluge.  It's necessary after all.
+	* src/dd.c (buggy_lseek_support): New function.
+	(skip): Use it.
+	Frank Adler reported that although _llseek returns 0, lseek
+	erroneously returns an offset suggesting the operation succeeded
+	even though it fails.
+
+	* install-sh: Double quote as needed, to protect against arguments
+	containing spaces or shell metacharacters.  Reported by Bruno Haible.
+
+2000-08-23  Jim Meyering  <meyering@lucent.com>
+
+	* tests/dd/not-rewound: New test, for the SEEK_CUR vs. SEEK_SET part
+	of the last change.  Based on Paul's example.
+	* tests/dd/Makefile.am (TESTS): Add not-rewound.
+
+2000-08-22  Paul Eggert  <eggert@twinsun.com>
+
+	* src/dd.c (skip):
+	Assume lseek failed if it returned zero, since a zero return is
+	impossible and some buggy drivers return zero.
+
+	Use SEEK_CUR rather than SEEK_SET; this fixes a bug when the
+	file descriptor is not currently rewound.
+
+2000-08-23  Jim Meyering  <meyering@lucent.com>
+
+	* src/dd.c: Back out my last change.  Paul's (above) is better.
+
+2000-08-22  Jim Meyering  <meyering@lucent.com>
+
+	Don't even try to use lseek on character devices.
+	* src/dd.c (buggy_lseek_support): New function.

+	Reported by Martin Gallant via Michael Stone.
+
+2000-08-21  Jim Meyering  <meyering@lucent.com>

+
+	* depcomp: Update from automake.
+
+2000-08-20  Jim Meyering  <meyering@lucent.com>
+
+	* Version 4.0y.
+
+	Add support for cp's new POSIX-mandated -H and -L options.
+	* src/copy.h (enum Dereference_symlink): Define.
+	(struct cp_options) [dereference]: Change type to Dereference_symlink.
+	* src/copy.c: Declare lstat.
+	(copy_dir): Set `xstat' member to lstat so that with `-H' we don't
+	follow symlinks found via recursive traversal.
+	Update uses of `dereference' to compare against new enum member names.
+	* src/cp.c (long_opts): Add --dereference, -L.
+	(usage): Describe -L and -H.
+	(cp_option_init): Initialize to DEREF_UNDEFINED, not `1'.
+	(main): Add `H' and `-L' to getopt spec string.
+	[case 'a']: Initialize `dereference' to DEREF_NEVER, not 0.
+	[case 'd']: Likewise.
+	[case 'H']: New case.
+	[case 'L']: New case.
+	[case 'R']: Don't set dereference to `0' here.
+	If it's not yet defined, set x.dereference to DEREF_NEVER
+	if -R was specified, else set it to DEREF_ALWAYS.
+	Set x.xstat accordingly for -H.
+	* doc/fileutils.texi (cp invocation): Describe -H and -L.
+	* src/mv.c (cp_option_init): Initialize to DEREF_NEVER, not `0'.
+	* src/install.c (cp_option_init): Initialize to DEREF_ALWAYS, not `1'.
+
+	* tests/cp/Makefile.am (TESTS): Add cp-HL.
+	* tests/cp/cp-HL: New test.
+
+	* src/du.c (print_totals): Rename global from opt_combined_arguments.
+
+2000-08-17  Paul Eggert  <eggert@twinsun.com>
+
+	* src/copy.c (DO_CHOWN): Do not make a special case for non-root.
+	POSIX.2 requires that cp -p and mv attempt to set the uid of the
+	destination file, even if you're not root.  This affects behavior
+	only on hosts that let you give files away via chmod.
+	* NEWS: Describe the above change.
+
+2000-08-15  Jim Meyering  <meyering@lucent.com>
+
+	* src/du.c (count_entry): Remember the current directory also for `.'
+	and `..'.  Reported by Stephen Smoogen, based on a patch from H.J. Lu.
+	* tests/du/two-args: Add tests for this.
+
+2000-08-14  Jim Meyering  <meyering@lucent.com>
+
+	* src/copy.c (copy_reg): Move declaration of local, `n_read', into
+	the scope where it's used.
+	(copy_internal): In calling copy_reg, pass not the raw `src_mode',
+	but the possibly-umask-relative mode, `get_dest_mode (x, src_mode)'.
+
+2000-08-13  Jim Meyering  <meyering@lucent.com>
+
+	* src/copy.c (get_dest_mode): Rename from new_nondir_mode.
+	Honor the umask for `cp', but not for `mv' or `cp -p'.
+	(copy_reg): New 4th parameter, dst_mode.  Pass it as 3rd arg. to open.
+	(copy_internal): Change type of locals `src_mode' and `src_type' from
+	int to mode_t.
+	Remove unnecessary local, `fix_mode'.
+	Combine two if-stmts into one.
+	Pass `src_mode' as 4th arg to copy_reg.
+	If we've just created a new regular file, return early, skipping the
+	chmod step.  copy_reg now sets permissions of such files upon creation.
+	Use get_dest_mode, so there's just one chmod call here.
+
+	* tests/cp/Makefile.am (TESTS): Add perm.
+	* tests/cp/perm: New tests, to help ensure the above didn't
+	change anything.
+
+2000-08-12  Jim Meyering  <meyering@lucent.com>

+2000-07-15  Jim Meyering  <meyering@lucent.com>
+
+	Begin converting "`%s'" in format strings to "%s", and wrap each
+	corresponding argument in a `quote (...)' call -- if there's only one.
+	If there are two or more, then use `quote_n (0, ...),
+	quote_n (1, ...), ...'.
+
+	Here's the justification, from Paul Eggert (thanks, Paul):
+
+	  [Consider] the following, taken from fileutils/copy.c:
+
+	     error (0, errno, _("cannot create directory `%s'"), dst_path);
+
+	  Now, suppose dst_path is "/'\nrm: removing all files under `/"
+	  (expressed in C string syntax).  This will cause the user to see
+	  the following delightfully ambiguous display:
+
+	    cp: cannot create directory `/'
+	    rm: removing all files under `/'
+
+	  It would be better to rewrite the above line to be something
+	  like this:
+
+	    error (0, errno, _("cannot create directory %s"), quote (dst_path));
+
+	  using the definition of "quote" [in lib/quote.c].  That way,
+	  the user will see the following unambiguous display instead:
+

+Changes in release 4.01:
+[4.0.31]
+* mkdir: fix a bug introduced in 4.0.30 whereby `mkdir existing-dir' would
+  succeed.  Now it fails, as it should (and used to).
+[4.0.30]
+* mkdir: fix a bug introduced in 4.0.28 whereby parent directories created
+  via `mkdir -p' would have permissions that did not account for the umask
+[4.0.29]
+* ls.c wouldn't compile on some systems: fix it
+* `cp -R --parents dir1/ dir2' failed on NetBSD, due to a portability problem
+[4.0.28]
+* ls is much more efficient on systems (e.g., linux-2.4.*) that store file
+    type information in directory entries.
+* shred now automatically determines the size of each block device argument
+* ls's date/time format strings are now local dependent
+* mkdir, mknod, mkfifo, and chmod work better in conjunction with ACLs
+* `cp --parents dir1/ dir2' no longer gets a failed assertion
+* shred now determines the size of block devices like /dev/fd0
+* `shred --exact file1 file2' now erases `file1', too
+[4.0.27]
+* install once again unlinks an existing destination before trying to open it
+* mv no longer gets a failed assertion when moving a directory (specified with
+    a trailing slash) from one partition to another, and giving it a different
+    name at the destination.
+* `cp --link -f src existing-dest' no longer fails (bug introduced in 4.0z)
+* cp's new --remove-destination option now works with -R
+[4.0z]
+* `cp -p' once again preserves `special' permission bits (this bug was
+    introduced in 4.0y)
+* mv's --force (-f) option now controls solely whether mv prompts (per POSIX)
+* `cp -f' now first attempts to open an existing destination file, and only
+    if that fails does it resort to unlinking the file and retrying the open.
+    Before, it would unlink the file before trying to open it.
+* cp accepts a new option, --remove-destination, that provides the old behavior
+* cp's -f option no longer cancels the effect of --interactive (-i) (per POSIX)
+* when ls sorts directory entries, it now honors the current locale settings
+* dd's `skip=BLOCKS' operator once again works on systems with a buggy lseek
+  function (Linux, at least on SCSI tape devices)
+* fix a typo in install-sh
+[4.0y]
+* cp now accepts the POSIX-mandated -H and -L options.
+* cp -p and mv now try to preserve uid even if you're not root, as per POSIX.2.
+  This affects behavior only on hosts that let you give files away via chmod.
+* du would fail when given `.' or `..' followed by other command line arguments
+* Using cp's short-named `-P' option evokes the warning that that the
+   meaning of `-P' will soon change.  Use `--parents' instead.
+* chgrp, chmod, and chown: when used with the --verbose option, might give an
+  invalid diagnostic (due to clobbered errno) when failing.
+[4.0x]
+* Fix cp so that `cp -r DIR1/ DIR2' works properly once again.
+* New ls option --quoting-style=clocale acts like --quoting-style=locale,
+  except that it quotes "like this" by default instead of `like this'.
 [4.0w]
 * When `cp -pR' fails to copy a file, it now preserves permissions, owner,
    and group of the containing directory.
