	time if `--' is given (POSIX-required kludge).

	* mkfifo.c: Remove -p +path option, no longer specified by POSIX.

	* cat.c: Remove -c option added for POSIX draft 9, since POSIX
	draft 10 removed it. 

	* tac.c (tac_stdin): Use fstat instead of lseek to determine
	whether stdin is seekable, because lseek silently fails on
	some special files, like tty's.
	tail.c (tail_chars, tail_lines): Use fstat instead of lseek;
	don't turn off -f for non-regular files (assume the user knows
	what he's doing; it might work for fifo's and sockets).

Wed Jul 11 12:10:33 1990  David J. MacKenzie  (djm at albert.ai.mit.edu)

	int == sizeof long and less efficiently but correctly if they
	are different sizes.
	(compare_ctime, etc.): Use longdiff.

	* ls.c (decode_switches): Make -k not imply -s, to allow the
	summary directory size printed by -l to be in 1k blocks
	without having the size of each file printed as well.
	(convert_blocks): Provide for systems with a blocksize that is
