The earlier fix for hoizontal vs vertical doors would have worked for
the Cav quest (lower left in leader's chamber) where door handling
occurs before wallification, but it wasn't working for minend-3 (east
wall of entry room) which already had walls. The more recent fix
solved the second case but broke the first one. I think this actually
solves both modes of door classification. I hope....
