New arg NEGATIVE.
(ceil_percent): Now returns double, not int.
Be more careful about adding 1 to a wild value.
(show_dev): Don't filter out wild sizes from the underlying operating
system; instead, show them to the user as faithfully as possible.
reuse) that would lead to a failed assertion.
Reported by Ken Pizzini.
(tail_forever): Record errno before using it in call to `error'
which might change it.
(tail_file): Likewise.
`mv src symlink-to-src' when src and dest are on different partitions.
Otherwise, that `mv' command would silently remove `src'.
Reported by Michael Stone.
(main): Define it.
(change_file_group): Use it. Before this change, when running chgrp
on a symlink without --dereference (-h) and when the requested group
is the same as the group for the *symlink*, chgrp would do nothing.
Now it changes the group of the file referenced through the symlink.
Reported by Martin Mitchell.
(STAT_LIKE_LINK): Define.
(do_link): Use STAT_LIKE_LINK, rather than bare `stat', and perform
the extra lstat only on systems where LINK_FOLLOWS_SYMLINKS.
(sortalloc, mergealloc, LINEALLOC): Use it.
(sortalloc, mergealloc, linelength): Now const.
(sortalloc): Increase from 0.5 to 8 MB.
(mergealloc): Increase from 16 to 256 kB.
(LINEALLOC): Increase from 0.25 to 4 MB.
Do not consider newline to be part of a line when comparing lines
in `sort' and `comm'. POSIX.2 requires that we consider newline,
but this is a bug in the spec and the bug will likely be fixed.

(anonymous enum) [LONG_FOLLOW_OPTION]: Define.
(long_options): Use LONG_FOLLOW_OPTION here, instead of 'f'.
(main): Remove the `::' after the `f' in getopt_long string.
Add `case LONG_FOLLOW_OPTION' after `case 'f':'.
Based on a patch from Tim Waugh.
Deprecate --version-control (-V) in comments.
(usage): Remove mention of --version-control.
(main): Make -V warn then fall through into --backup case.
[--backup case]: Handle optional arg.

(open_maybe_create): Remove.
(touch): Don't record whether the file was created; this isn't
possible to do reliably and portably without race conditions.
If the file was created and if amtime_now is nonzero, this
change means we'll have to do another utime system call, but
that's no more harmful than the previous version of this code.

(usage): Remove mention of --version-control.
(main): Make -V warn then fall through into --backup case.
[--backup case]: Handle optional arg.
(TARGET_DIRECTORY_OPTION): Define.
(SPARSE_OPTION): Define.
(usage): Describe it.
(do_copy): Change meanings/names of first two parameters: use `n_files'
in place of `argc - optind', and `file' instead of `argv + optind'.
Add parameter, target_directory.
(main): Pass new arg, target_directory.
