slash2toslash2.2 no longer converts polls
correctly since pollquestions.sid was changed to
stories.qid. fix it. test it.
yes, this is just one of many changes that will have
to be made before we rename it to
"slash2toslash2.4". shouldn't that be
"slash2.0toslash2.4"? do we even need such a
beast or do we just need "slash2.2toslash2.4"?
