displacing grid bugs (trunk only)

Browse Source 
From a bug report, you could swap places with a pet grid bug when
you're making a diagonal move.  Now you can't.  [Completely ignored:  it
is possible to swap places with pets which are incapable of movement....]

     This imposes the same restriction on the astral Riders when they're
exchanging places with monsters in their way.
