Subject: Add debugging of arrow paths
X-Git-Tag: 1.8~3
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=493865da581f5d10901bad2f3e4af36217dd43cc;p=wumpus.git

Add debugging of arrow paths

Add debugging statements that print out the location of the arrow and
the rooms it is supposed to move to.  The statements use conditional
compiling using the DEBUG macro.
