In order to get its legacy encoding when working with Greek, babel adds
two commands \greektext and \latintext (which I have to empty in order
to use them with XeTeX).

I guess all it should be done is redefining these commands so that they
will be able to switch scripts. Is it possible to switch the script
without having to select a font?
