6c1426fd14 Get the column affinities right when processing an IN operator where 
the right-hand side is a subquery with an ORDER BY clause.  Ticket #2295.
This bug has likely been present since version 3.0.0 and it has just now
been noticed, so it seems to be a obscure case. (CVS 3837)

look for other related problems before closing this ticket. (CVS 3835)
