Yes.  However, the NetBSD doc specifically says that getopt returns -1
and the FreeBSD doc says EOF.  While they are both the same in this
implementaiton, pedantically, FreeBSD should use -1.  This change
won't break anything, since EOF does == -1 (assuming that other lite2
deltas don't impact this).
