There should only be two changes in behavior:
arogue7/fight.c, arogue7/fight.c: a to-hit bonus is now correctly
applied to characters who are not monks instead of monks who are not
empty-handed.
urogue/fight.c: fixed an interaction with the "debug" macro that could
cause the wrong message to be displayed.
Marking non-magic items caused segfaults because item_color was set to
NULL. item_type could also be used as an out-of-bounds index. These
problems have been fixed by only using these variables when the mark
argument is false, in which case they are properly initialized.
A fall-through case statement was also fixed.
