	* cp.c (copy): Test for temporarily modified permission mode
	  after the other test, so that `-p' work for files whose mode
	  needed a temporary mode change.

	  assume `-s' if this is so.

	  Always copy fifo's and symbolic links as themselves.

	  find frist non-zero byte.  This to avoid false hole

	  the switch statement, so all file types are copied correctly
	  even in a non-recursive copy.
	* cp.c (copy): Return after having created a symlink, since
	  chmod and utimes dereference, and would affect the symlink
	  target.  Remove test for symlinks after switch.

Sun Feb 25 18:31:09 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* Makefile: Compile ls after vdir so systems with a cc that

	* ls.c (print_long_format): Always print the group, for POSIX.
	(decode_switches): Make -g option a no-op for BSD users.

	(main): Recognize new -d +directory option to allow superuser to
	make hard links to dirs, like the BSD ln -f option.

	* rmdir.c (main): Remove trailing slashes from args (added by
	shell file completion but the rmdir syscall can't handle them).

	uniformity with rmdir (you can't do file completion on dirs
	that haven't been made yet . . .).

	* mv.c: Rename global var `nargs' to `args_left' to avoid
	conflict with undocumented BSD libc function (the new name is
	clearer, anyway).

Tue Feb 20 17:09:19 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* dd.c: Use new global var `program_name' in error messages
	instead of hardcoded "dd".

	from argv[0].
	(basename): Function removed.

	* rm.c (main): Don't strip leading dirs from argv[0].

Sun Feb 11 17:50:29 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* chmod.c (usage): Add yet another ellipsis.

Sun Feb 11 16:41:30 1990  Jim Kingdon  (kingdon at pogo.ai.mit.edu)

	* cp.c (copy_reg): Use HAVE_FTRUNCATE to decide whether to
	use ftruncate().
	(main): Use GETGROUPS_MISSING to decide whether to use getgroups().
	[hpux || !USG]: Define HAVE_FTRUNCATE.
	[USG && !hpux]: Define GETGROUPS_MISSING.
	mv.c (rename): Put in #ifdef RENAME_MISSING not #ifdef USG.
	(do_move): Use FCHMOD_MISSING to decide whether to use fchmod().

	rather than by the offset of the first differing bytes, before
	producing output.
	Replace if-else-if constructions with case statements for clarity.
	(bcmp2): Rename `n' to `nread'.

Fri Feb  9 10:25:03 1990  David J. MacKenzie  (djm at rice-chex)

	* mv.c (movefile): Remove trailing slashes from FROM (some

	the rename syscall to fail).

Thu Feb  8 22:50:12 1990  Torbj|rn Granlund  (tege at sics.se)

	* cp.c (copy_reg): Change error handling after lseek, since
	  this is a fatal error.  Also change error message to
	  something more generally understood.

	* cp-aux.c (error): Use FATAL to recog fatal errs.

Thu Feb  8 21:25:40 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	* ln.c: Remove incorrect comment.

	* cp.c, cp-aux.c (usage): Change +dereference option to
	+no-dereference, since dereferencing is done by default and
	the option turns it off.

	* Version 1.0 released.
