This is done

The mercurial backend is broken when no changelog message is given.

Here is a quick patch, partialy copying the svn backend.

    $message = possibly_foolish_untaint($message);

The svn backend puts the user info in the message because that's the only way to store the user info, unlike with mercurial. The svn plugin also removes that info when getting the RecentChanges info. Since mercurial does not do that, it seemed better to me to test for an empty message and set it to a dummy commit string, which I've done. --Joey

Thanks for the correct fix, Joey. --hb
