The automatic annotations supplied for various special levels were
treating the quest leader's summons as being mutually exclusive with
the other things of interest. It's not, so wasn't shown if the entry
portal was on either the bigroom level or the rogue level. Handle it
differently from the rest so that it can stack with annotations for
those levels. (The annotation for the portal itself, which doesn't
get added until traversed, was already handled differently and shown
correctly on those levels.)
