Looking at where in _main_complete I would need to add this, it seems
that it could be done with a post function setup from a completer which
would be like _all_matches. Your suggestion is probably better though.

I tried this:

  if [[ $compstate[insert] = *menu* && "$compstate[nmatches]" -gt 1 &&
      -n $PREFIX$SUFFIX ]]; then
    _description -V original expl original
    compadd "$expl[@]" -U -Q - "$PREFIX$SUFFIX"
  fi

There needs to be more things in the if condition though. In
particular, it has problems when the matches added are added after part
of PREFIX will have been moved to IPREFIX, e.g. cd Mail/<tab> results
in the slash being removed. Any idea on how to get it working or if it
is even possible? If not, I'll commit the _match change instead.

That didn't seem to work but compstate[insert]=all does the job. Hence
the following patch.

Thanks Sven.
