Based on an IRC discussion I changed the smart placing mechanism to hit also if icccm.request_pos is true. Many Gnome based application try to start with coordinates below the shelfes and E allows it. This smoothly moves this windows away is smart placement is active. It's not as aggressive as Metacity, but now usable with vertical shelfes. If you don't like this change hit me and discuss it again on the list.
