NetBSD/games/hack/hack.mkshop.c
chuck 88c6198c95 shops are only supposed to have 1 door (as per standard hack 1.0.3).
for some reason, the version of 1.0.3 that was in the 4.4 lite tree
was modified to allow shops with two doors -- this violates the spirit
of the game.   with this diff, we revert back to classic 1.0.3 behavior.
