1) Don't put two pits in the same room.
2) Don't put bats and pits in the same room. (you will never hit the bat)
3) Don't start the player in a room with a pit or bad, if possible. Some
caves are so crowded the loop may go on forever, so we give up after 100
tries to put them in a safe location (as long as it's not with the wumpus).
4) Make the manpage reflect reality WRT the default number of rooms.
Bug #3 pointed out by salo.
games in a row. Also modify change made in rev 1.18 to work correctly.
take_action() returns 1 if the player dies, causing the game to allways
exit after any death, now the game correctly asks if the player would
like to play again.
Games which run setgid from dm, but don't need to, should drop their
privileges at startup.
Games which have a scorefile should open it at startup, then drop all
privileges leaving just the open writable file descriptor. If the
game can invoke subprocesses, this should be made close-on-exec.
Games with scorefiles should make sure they do not get a file
descriptor < 3. (Otherwise, they could get confused and corrupt the
scorefile when using stdin, stdout or stderr.)
Some old setuid revokes from the days of setuid games change into gid
revokes.
