Yes, this is a side effect of the AI added as a result of the
<vafu1zmu3hm.fsf@INBOX.auto.gnus.tok.lucy.cs.uni-dortmund.de> thread,

I think the patch I proposed works equally well in practice, and gives
less surprising results in the corner cases.  Maybe you can run with
this for a while and see if it works?  (The patch is againt current
CVS.)
