If so, how did the listview work at all until now?!?

Good stuff, maybe we should link to it from WineHQ

Almost. If it does go in though, we need to:
-- fix a few more places where we look at WS_[VH]SCROLL
-- understand why did the listview work at all if the LVS_ stuff was missing
-- do an audit (or add a Janitorial task) to audit and fix the
other controls as well.
(of course, only the 1st point is really needed for the patch to go in,
but the other two would be nice to have).
