Forgot to change the second argument of ilistmatches().

That's the compstate[insert] behaviour I described when I implemented
it. I'm pretty sure I asked if this space should be there or not at
the time, and here seems to be the answer to that question.
So the patch makes the space not be inserted in this case.
Btw. I was thinking about cases where one selects one match from those 
generated and wants to insert only that -- leaving completion. In such 
a case the space is the right thing, so I may enhance the use of the
insert key some day to be able to select both.

That test at the end of do_ambiguous() is one of the things I started
to dislike long ago...

Hm, works for me (note: only completions inserted with
accept-and-{menu-complete,hold}).
