84 * didn't have modes, so it was an undocumented noop.
85 * In FreeBSD 3.0, lchmod(2) is introduced and this
86 * option does real work.
92 * "-[rwx]" are valid mode commands. If they are the entire
93 * argument, getopt has moved past them, so decrement optind.
94 * Regardless, we're done argument processing.
