The problem here is this will give you what I had been getting yesterday
when playing with this. In the case that the unambiguous bit is shorter
than the word on the command line, the extraneous stuff is deleted from the
command line. This certainly isn't what I wanted (maybe someone does
though) - I just wanted it to do nothing at all, leaving me to either edit
the line or invoke menu selection. In order to get that to happen, the
following chunk of code I purloined from _match is essential:

      [[ "$compstate[insert]" != *menu ]] &&
        compstate[pattern_insert]= compstate[insert]=

Sounds like something that's better left alone to me. Presumably the
returning 1 is to get zsh to ring the bell. Perhaps a note on this in the
info pages would be the best solution.
