PatR 5457cbe0e3 liquid_flow when digging pit 
Part of github issue #338 that isn't about shops:  objects at the
spot where a dug pit fills with lava (or water) weren't being
effected by that.

While fixing it, I noticed that hero's steed wasn't affected either.
Also, when conjoined pits are filled in, monsters other than the
steed are at risk but weren't being handled.  Presumably they fell
in on their next move.
