Thanks.
You do realize that calling 'message' in a display-spec form causes us
to re-enter redisplay in the middle of redisplay? I didn't even know
we allowed that, but there's something new about our display code to
learn every day.
Should be fixed now.
P.S. Is there a chance fontification-functions will also call
'message'? Because I think we have the same problem there.
