Fix githib issue #121 - shopkeepers don't charge for consecutive
acts of vandalism on the same square. pay_for_damage() keys its
action on the 'when' field of the damage structure, and when a
second type of damage gets added to existing damage, that wasn't
being updated. Both bits of damage (broken door or dug wall plus
trap created at same spot) get repaired together but shopkeeper
wasn't challanging hero to pay for the second one (trap).
The repair process had issues too. If you broke a shop door, paid
off the shopkeeper, then left the level before the repair took
place and came back after (or rather, catching up for lost time
repaired it when you returned to the level), it didn't actually
get fixed and remained a doorless doorway that was considered to
have been successfully repaired (record of damage discarded).
Unless there was also a trap there; then the door did get properly
fixed when the trap was removed.
Object scattering during wall repair was bypassed if trap removal
took place.
Also, trap removal while off level still gave messages when it took
place after you returned. I didn't try to verify that; it's possible
that vision is in a state where you can't see the repair even if you
return to a spot where it would be visible. But the return value
from the repair routine was one which wanted a message instead of
the one to suppress messages.
Not addressed: digging a pit inside a shop (aside from in doorway
or breached wall) is not treated as damage which should be repaired.
This includes the case of digging up a grave which converts the spot
into ordinary floor (plus pit trap).
