[Spambayes] Maildir fix.

Thanks very much for this.  We'd already had this reported - a patch was
checked in a week or so back.

mboxtrain v1.17 (09/07/03) fixes this.  You can keep using the patched
version you've made, or drop the latest version from cvs, whichever
suits you.  This will make it into the next source release.
