Au, verflucht. _main_complete forced listing when a _message was added 
and there were less than two matches. Unfortunately, it forced
message-only listing, so the option just wasn't shown.

The patch will make it show the message and the option, which is what
should have been done before. If this is good or if it should only
complete the option is a different question. Hm. Hm?

Bye
