could cause the removal of that directory to fail with an erroneous
diagnostic about a directory cycle. Reported by Vineet Chadha.
(AD_pop_and_chdir): If the directory we're about to
leave (and try to rmdir) is the one whose dev_ino is being used to
detect a cycle, reset cycle_check_state.dev_ino to that of the parent.
(wrap_write, do_encode, main): Change type of
parameters and locals, wrap_column, form size_t to uintmax_t.
(main): Adjust to use xstrtoumax, accordingly.
<string.h>, <stdlib.h>, <stdbool.h>, <limits.h>, <errno.h>.
Include "system.h" before the other lib/*.h header files.
Include <sys/types.h> before "system.h".
(wrap_write): Remove declaration of unused local, initial_column.
(main): Prefer dirent.d_ino to stat when possible.
(gobble_file): Add inode argument.
(print_dir): Pass inode if available.
(usage): Remove inaccuracy.
(interactive_type): New enum.
(long_opts): Let interactive take an optional argument.
(interactive_args, interactive_types): New option arguments.
(usage): Document -I, --interactive=WHEN. Use program_name
instead of a basename.
(main): New -I option, new behavior to --interactive.

(close_preserve_errno): New function.
(fd_to_subdirp): Don't print a diagnostic in this function.
Do it from the callers instead, unless rmdir succeeds.
(remove_cwd_entries, remove_dir): Adjust callers.
the same directory more than once in the hierarchy beneath a single
command-line argument. That is legitimate, e.g. when there are
two or more symbolic links, each pointing to some directory that
would not otherwise be copied. Reported by Christophe LYON.
to put a regular file in O_NONBLOCK mode fails with EPERM.
That happens on Linux when using tail -f on a file with the
append-only attribute. Reported by Dean Gaudet. For details,
see http://savannah.gnu.org/bugs/?func=detailitem&item_id=15473.
Don't include "lchown.h".
(restricted_chown): Accept a new parameter, CWD_FD, and use it in
calling openat, lchownat, chownat, rather than open, lchown, chown.
Update caller.
its clients accordingly -- note that du.c uses fts but doesn't need
any adjustment, since it doesn't operate on the actual files,
but rather just uses the stat buffers provided by fts.
Include "openat.h".
(process_file): Use chmodat (fts->fts_cwd_fd,... in place of chmod (...
