(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.
(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.
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.
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)'.
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.
(iswprint, mbrtowc, wcwidth): Provide default definitions.
(total_bytes): New variable.
(print_bytes): New variable.
(longopts): Change abbreviation for --chars from 'c' to 'm'.
(usage): Update.
(write_counts): Add `bytes' argument.
(wc): New variables `bytes', `count_bytes', `count_chars',
`count_complicated'. The old code determines `bytes', not `chars'.
New case for MB_CUR_MAX > 1. A non-printable non-space character does
not increment the line position or start a word. Update `total_bytes'.
(main): Initialize `print_bytes' and `total_bytes' to 0. Accept 'm'
option. Pass `total_bytes' to write_counts.
(long_opts): Update "parents" and deprecated "path" entries to use
`PARENTS_OPTION', not `P'.
(usage): Update --help output.
(main): Warn that the meaning of `-P' will soon change.
Allocated buffer was sometimes too small.
Reported by Greg McGary (who found this bug using his
bounded-pointers-enabled gcc).
(init_header): Move declarations of several variables into the
inner scope where they are used.
