[racket] Bug report: collects/htdp/hangman.rkt

I've fixed the problem that was introduced when signatures were added,
but there seem to be other problems with the teachpack.

If someone would be kind enough to provide a test case (a sample
non-"solution" that at least runs) I'll keep working on it and put it
into drdr so that we don't have this problem going forward.
