I've decided to do the latter. I.e. one can now put `messages' in
$compstate[list] to make it show only the messages. This can be
combined with `explanations' to show both types (but not the matches
themselves).

The former (force listing if messages were added) can then be
implemented in shell code, see _complete_debug for an example.
