With X11Forwarding off by default, one would assume that it is only
enabled on a case-by-case basis for users or groups who already have the
necessary privileges to run arbitrary code on the server and therefore
have nothing to gain from exploiting this bug.  With X11Forwarding on by
default, it might remain enabled for e.g. gitolite users.
