Sadly, there is no portable way to reset getopt(3).  POSIX is silent
on the issue.

The BSD way is:
        optind = 1;
        optreset = 1;

The GNU way is:
        optind = 0;

These are mutually exclusive on the application side.  OpenBSD's
getopt supports both and tog.c uses a nonsensical mix.

We should make up our mind and go with one or the other.  I don't
really care which one to choose, some platforms will require a patch
either way, but the BSD scheme has the minor advantage that optreset
will trigger a compile error if unavailable, while lack of support
for optind=0 will only manifest at run time.

The fact that we mix getopt_long() and getopt() does not affect
this, although switching everything to non-POSIX getopt_long() and
optind=0 would also take care of it.  (Alternatively, do we need
getopt_long at all?)

Death by a thousand papercuts...
