You're right. I got mixed up. I still don't like that last line in
_guard though. I think that maybe when _guard returns 0, matching
options should still be offered so a -c3nf option could be matched and
options would be offered after pine -c without that last line in _guard.
The important original point was really what happens when _guard returns
1 and that is now right.

Apart from the minor point above, I am now happy that this all works so
thanks Sven. Sorry for being slow about replying to this last e-mail

It can't really be handled by anything else unless there is a specific
maximum to X display numbers allowing us to add all possibilities.
_guard is actually particularly valuable in the non-option argument case
because before the recent changes options would not complete. The
problem really is that the _guard patterns have to match fully, not
partially: _vnc can be fixed by using the pattern (|:[0-9]#) which I'll
commit later if _guard stays as it is.
