hfs-pit
=======
Creates a pit to the underworld at the cursor.
Takes three arguments: diameter of the pit in tiles, whether to wall off
the pit, and whether to insert stairs. If no arguments are given, the default
is ``hfs-pit 1 0 0``, ie single-tile wide with no walls or stairs.::
hfs-pit 4 0 1
hfs-pit 2 1 0
First example is a four-across pit with stairs but no walls; second is a
two-across pit with stairs but no walls.
