Fixed.  It was a trivial buffer overflow that would have been caught if
the CFLAGS had only included -Werror=format.

To find the cause and fix it, I did this:

cd games/xpipeman
bmake configure
bmake build-env
make CFLAGS="-O0 -ggdb"
^D
bmake install
gdb --args work/xpipeman/xpipeman
r
where

This told me that sprintf was called from main.c:324.  The rest was
simple character counting.
