Those were useful when tests might have been run in the same directory and in parallel. Now, each test is run in a newly- created empty directory. * tests/cp/backup-1: Remove obsolete uses of "$$". * tests/cp/same-file: Likewise. * tests/dd/misc: Likewise. * tests/mv/part-symlink: Likewise. * tests/mv/to-symlink: Likewise. * tests/touch/fail-diag: Likewise.
