Don't invoke a program more than once.

function `down' so that it precedes definition of tac_nonseekable.

(copy_to_temp): Renamed from save_stdin, since
now it copies a general file descriptor, not just stdin.
(tac_nonseekable): Renamed/adapted from tac_stdin.
(tac_file): Get fd via `open' directly rather than via fopen/fileno,
since we never used the stream. Perform "-" to stdin mapping here
rather than in main. Determine whether a file is seekable,
by trying to `lseek' to its end, and dispatch to tac_seekable or
tac_nonseekable accordingly.
(main): Rewrite argument handling now that it uses only tac_file.

(rm): Destroy the saved_cwd here (via cwd_state),
if necessary, not in remove_dir. Otherwise, removing multiple
`.'-relative nonempty directories no longer worked.

operating on too many command-line-specified nonempty directories.
(remove_dir): Destroy the `struct saved_cwd' on the
top of the stack before returning. This usually closes the file
descriptor that was used to return to the original working directory.

warning from gcc-3.3.5 about a format not being a string literal.

Change "path" to "file name" whenever possible.
Remove usage comment, as it was a duplication of the code or doc.
Include <wchar.h> if available.
(mbrlen, mbstate_t) [! (HAVE_MBRLEN && HAVE_MBSTATE_T)]: Define.
(NEED_PATHCONF_WRAPPER, PATH_MAX, PATH_MAX_FOR, NAME_MAX,
pathconf_wrapper, portable_chars, dir_ok): Remove.
(NAME_MAX_MINIMUM, PATH_MAX_MINIMUM): New macros.
(pathconf, _PC_NAME_MAX, _PC_PATH_MAX): Define if nonexistent.
(portable_chars_only): New arg FILELEN.
Don't assume ASCII; we might be on an EBCDIC host.
Don't assume unibyte locale in diagnostic.
(component_start, component_len): New functions.
(validate_file_name): Renamed from validate_path. All uses changed.
Pretty much a complete rewrite.
Don't make copy of file arg. Always append trailing slash to
pathconf arg, just in case it's a symlink (this is pure paranoia;
we don't know of any hosts where the trailing slash is required).
Use size_t instead of long int when possible.
Avoid need to call pathconf in most practical cases.
Don't use euidaccess several times to test searchability;
just use lstat once. Reword diagnostic to put the (often very long)
file names last.

and both cvs and cvsu handle the former.

(file_ignored): Renamed from file_interesting, with
inverted return value. Accept the file name, not a struct dirent *.
All uses changed. Avoid the expense of calling fnmatch if the
file is ignorable due to leading '.'.
(all_files, really_all_files): Removed; replaced by:
(ignore): New variable. All uses changed.
(IGNORE_DEFAULT, IGNORE_DOT_AND_DOTDOT, IGNORE_MINIMAL, HIDE_OPTION):
New constants.
(hide_patterns): New variable.
(long_options, decode_switches, file_ignored, usage):
Add support for --hide.
(patterns_match): New function.
(usage): Replace "hide" with "ignore" in explanation, to avoid
confusion.

human-readable output has a byte count equal to its column width;
this isn't always true in locales where the radix character is not
'.' or ','.
(format_user_or_group): Revamp code to match the above fix;
this avoids the (very faint) possibility of integer overflow.

for obsolete option followed by non-obsolete, or by more
than one file. When obsolete, conform to SUSv2 rather than
original POSIX 1003.2-1992, as SUSv2 corrected the case of
"tail -c". Add support for the SUSv2 "b" modifier.
