Noone forces you to use the ddb hangman. In the past, care has been
taken to make "h" invoke "help" rather than "hangman" to prevent
accidental invocation.

Once you are in hangman in ddb, you are expected to be able to solve the
game.

You can improve your ddb hangman skills by practicing in usermode using
/usr/games/hangman -k or /usr/games/hangman /bsd (both may require
privileges to be able to read the symbol table).
