Yeah, the bull rush results need to be clarified a bit. Like when you push someone into a wall, or into an occupied space.
Right now, the only precedents I'm aware of are the results of a failed bull rush where your own square is occupied(fall prone), and the tactical manuver "domino rush"(push foe into another foe, trip attempt against both).
It seems reasonable to treat being pushed into a wall as falling damage, and pushing a foe into an occupied space as being prone. But I've not seen any official ruling about either.
