cp(1) bug
Wed Nov 25 19:15:37 EST 1981 (reported by swatt)
[ ]	"cp" when faced with a source argument which is a
	directory copies the data of the directory file into
	a plain file in the destination area.  This is
	obnoxious; either it should allow recursive copying
	of directory trees or it should ignore directory
	source arguments.  Fix is:

	cp /usr/src/cmd/cp.c /tmp/upd.$$.tmp ; chmod +w /tmp/upd.$$.tmp
	ed - /tmp/upd.$$.tmp <<\!xxFUNNYxx

		/* Is source a directory? if so, skip it.
		 * Probably more reasonable action would be to
		 * copy contents of directory if -r flag set
		 */
		if ((mode&S_IFMT) == S_IFDIR) {
			close (fold);
			fprintf (stderr, "%s is a directory (ignored)\n", from);
			return;
		}
