Alias iseek=N to skip=N, oseek=N to seek=N (Bug#45648).
* src/dd.c (scanargs): Parse iseek= and oseek=.
* tests/dd/skip-seek.pl (sk-seek5): New test case.
Do not allocate I/O buffer if copy_file_range suffices.
* src/copy.c (sparse_copy, lseek_copy): Buffer arg is now char **
instead of char *, and buffer is now allocated only if needed.
All uses changed.
It's more common to use bold style than not,
for references to other man pages.
Ideally each man page renderer would highlight references,
but currently some rely on styles in the page itself.
* man/help2man: Implement a --bold-refs option that
will mark up references like "name(1)" with bold
style around the "name" component.
* man/local.mk: Pass --bold-refs to our help2man unless disabled.
* configure.ac: Add a --disable-bold-man-page-references option.

COLORTERM is an environment used usually to expose truecolor support in
terminal emulators. Therefore support matches on that in addition
to TERM. Also set the default COLORTERM match pattern so that
we apply colors if COLORTERM is any value.
This implicitly supports a terminal like "foot"
without a need for an explicit TERM entry.
* NEWS: Mention the new feature.
* src/dircolors.c (main): Match COLORTERM like we do for TERM.
* src/dircolors.hin: Add default config to match any COLORTERM.
* tests/misc/dircolors.pl: Add test cases.
Problem reported by Dan Jacobson (Bug#48248).
* doc/coreutils.texi (tr invocation): Improve documentation for
tr's failure to support multibyte characters POSIX-style.
* doc/coreutils.texi (tr invocation), src/tr.c (usage):
Use terminology closer to POSIX's.
* NEWS: Mention the new feature.
* doc/coreutils.texi (dircolors invocation): Describe the new
--print-ls-colors option.
* src/dircolors.c (print_ls_colors): A new global to select
between shell or terminal output.
(append_entry): A new function refactored from dc_parse_stream()
to append the entry in the appropriate format.
(dc_parse_stream): Adjust to call append_entry().
* tests/misc/dircolors.pl: Add test cases.

related to coreutils commit v9.0-143-gabde15969
we no longer maintain numeric IDs through chopt->{user,group}_name.
Therefore we need to adjust to ensure tests/chown/basic.sh passes.
* src/chown-core.c (uid_to_str, gid_to_str): New helper functions
to convert numeric id to string.
(change_file_owner): Use the above new functions to pass
numeric ids to describe_change().
This also affects ls -v in some corner cases.

While looking into this, I spotted some more areas where the
code and documentation did not agree, or where the documentation
was unclear. In some cases I changed the code; in others
the documentation. I hope things are nailed down better now.
* doc/sort-version.texi: Distinguish more carefully between
characters and bytes. Say that non-identical strings can
compare equal, since they now can. Improve readability in
various ways. Make it clearer that a suffix can be the
entire string.
* src/ls.c (cmp_version): Fall back on strcmp if filevercmp
reports equality, since filevercmp is no longer a total order.
* src/sort.c (keycompare): Use filenvercmp, to treat NULs correctly.
* tests/misc/ls-misc.pl (v_files):
Adjust test to match new behavior.
* tests/misc/sort-version.sh: Add tests for stability,
and for sorting with NUL bytes.
* src/system.h (emit_ancillary_info): While supported if entered
manually, the "[" character is not highlighted as part of a
URL by default in terminals, so avoid using it.
Addresses https://bugs.gnu.org/53946
* src/system.h: Adjust the alignment of the --help
and --version option descriptions, to start at column 21.
This better aligns with the descriptions of most commands,
and also aligns with the minimum column a description must
start at to ensure a blank line is not output when a description
follows an option on a line by itself.
* src/rmdir.c (usage): Move description to column 21,
so that a --long-option on its own line without a
trailing description, doesn't have an erroneous blank
line inserted between the option and description.
Also group descriptions with blank lines rather than indents,
so that man pages don't have erroneous blank lines
added within the description.
Addresses https://bugs.gnu.org/53946
* src/ls.c (usage): Use blank lines to group multi-line
option descriptions, rather than indenting.
This results in more consistent alignment of descriptions,
and also avoids erroneous new lines in generated in man pages.

* doc/coreutils.texi, doc/sort-version.texi:
Capitalize “Coreutils”.
* doc/sort-version.texi: Don’t emphasize natural sort so much,
since Coreutils has just version sort.
Use the term “lexicographic” instead of “alphabetic” or “standard”.
Suggest combining ‘V’ with ‘b’, and show why ‘b’ is needed.
Use shorter titles for sections, as GNU Emacs displays info poorly
when titles are too long to fit in a line.
Use @samp instead of @code for samples of data.
Do not use @samp{@code{...}}; @samp{...} should suffice and
double-nesting looks bad with Emacs.
Omit blank lines in examples that would not be present
in actual shell sessions.
Quote with `` and '', not with " or with '.
Mention dpkg --compare-versions more prominently.
Don’t rely on "\n" being equivalent to "\\n" in shell args.
Prefer Unicode name for hyphen-minus.
* doc/coreutils.texi (date invocation): Remove @var{...} usage,
as that capitalizes in the representation and thus somewhat
ambiguates the format wrt Month and Minute. This also avoids
a syntax check failure about redundant capitalization in @var{}.
Problem reported by Dan Jacobson (Bug#51288).
* doc/coreutils.texi (date invocation, Setting the time)
(Options for date):
* src/date.c (usage): Improve doc.
Problem reported by Vladimir D. Seleznev (Bug#53631).
* src/id.c (main): Do not canonicalize user name before
deciding what groups the user belongs to.
* configure.ac: Move the single-binary code before the
gcc-warnings code, so that the latter can depend on the former.
Suppress -Wsuggest-attribute=noreturn with single binaries,
to avoid diagnostics like the following:
src/expr.c: In function 'single_binary_main_expr':
error: function might be candidate for attribute 'noreturn'
Problem reported by Pádraig Brady in:
https://lists.gnu.org/r/coreutils/2022-01/msg00061.html
* src/basenc.c (finish_and_exit, do_encode, do_decode):
* src/comm.c (compare_files):
* src/tsort.c (tsort):
* src/uptime.c (uptime):
Mark with _Noreturn. Otherwise, unoptimized compilations may warn
that the calling renamed-main function doesn't return a value,
when !lint and when single-binary.
* src/dd.c (parse_integer): Avoid undefined behavior
that accesses an uninitialized ‘n’ when e == LONGINT_INVALID.
Return more-accurate error code when INTMAX_MAX < n.
* src/hostname.c (sethostname): Provide a substitute on all
platforms, to simplify the mainline code.
(main): Simplify. Remove an IF_LINT.
Use main_exit rather than return.
* src/factor.c (factor_using_squfof) [USE_SQUFOF]:
Use plain assert (...), not IF_LINT (assert (...)).
This code is currently never compiled or executed,
so this is merely a symbolic cleanup.
