`tac /proc/modules' would print nothing
(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.

(Standards conformance): Use "head -10" rather than "head -1" as
example of obsolete usage, since the POSIX consensus is that "head -1"
could be supported even if we don't yet have clear consensus on "head
-10". See today's revision to the SUS FAQ

Correct my patch of 2004-10-18.
(rm): Destroy the saved_cwd here (via cwd_state),
if necessary, not in remove_dir. Otherwise, removing multiple
`.'-relative nonempty directories no longer worked.

Plug a leak that would cause rm or a cross-device mv to fail when
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.

(validate_file_name): Give a more descriptive
diagnostic when pathconf fails. This also avoids an unwarranted
warning from gcc-3.3.5 about a format not being a string literal.

Remove usage comment, as it was a duplication of the code or doc.
Include <wchar.h> if available.

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.

OS limits, not file system limits. Component length checks
apply to all components, not merely to existing ones. Say
that nonexistent names are not errors. For -p, omit all
checks based on the underlying file system, not merely length
checks. Explain what the portabile file name character set is.

to a failed fchdir or failed fts_safe_changedir call, set
`sp->fts_cur = p'. Do this by removing the explicit `return NULL;'

to the common-case code below. Otherwise, after such a failure,
calling fts_close would attempt to free an already-freed buffer.
