That figures: Emacs needs uni-bidi for display, and `message' enters
redisplay.

Evidently, it isn't.  I think it is pulled in when charprop is loaded,
but that's half-way down loadup.el.

We need to find a way of loading uni-bidi and uni-mirrored before
loading loadup.el.  I will get to that later today, if no one beats me
to it.

And I still wonder how come this works in a GUI session.
