If a list wasn't displayed, it should do what it currently does, displaying
the relevant list for the active completion.  It's extremely minor --- I
have autolist on, so I get the list willy-nilly.

It does fix the problem, thanks.  _oldlist was the reason I needed to hit
^D twice.  Setting the old-list style should fix this, although I haven't
worked out if that's going to make me cross somewhere else.  So at the
moment everything is now working.
 
The completers I had, by the way, were

zstyle ':completion:*' completer _oldlist _expand _complete _approximate
