getopt used to sort the long option names, in an attempt to simplify

the logic.  That resulted in a bug.  My previous getopt checkin repaired
the bug but left the sorting.  The solution is significantly simpler if
we don't bother sorting at all, so this checkin gets rid of the sort and
the code that relied on it.
