Description
The most common case of this is when you duplicate a player-pushable
element onto a player, which ends up calling the TouchProc against
the source element with a direction equal to the player's movement
direction.
Another case is performing a `#go idle` in a scroll.
Either way, both of these will no longer crash ZZT.
This does not, however, prevent the player from moving onto a duplicator's destination on the same tick that the duplicator fires and then the duplicator source ends up moving based on the player's move direction. That is a different bug which typically doesn't crash the game.
(by GreaseMonkey)
In particular, this amends ElementPushablePush to not call itself if deltaX and deltaY are both equal to 0.
