Can you actually rename the user? I get a KeyError: 'No key
(username) value "anonymous" for "user"'. Anyway, I'm just
wondering why your patch also disallows viewing the
anonymous user? That isn't a security risk, isn't it?

Also, note that your patch makes the anonymous user
uneditable, even for admins. I can't think of a reason to
edit the anonymous user, so this probably not a problem though.
