Used by the routine at move_player_walk.
First adds in the nudge in +$0E and +$0F, which an archway leaves there (arch_nudge_loop) to steer the player towards the middle of the arch, and clears it. Then dispatches on the facing to add 3 units in that direction. The nudge is only ever used when the player is walking.
