Sorry, there is a misunderstanding.
I was starting my letter with "Not considering bustrophaedon", which means
not considering it!
I was speaking of the default behaviour of the script to be able to be
written EITHER rtl OR ltr, (and NOT bustrophaedon).
So the question is, again, DISREGARDING bustrophaedon (which I still believe
is actually a non-issue, as I put it in a longish mail in reply to Gábor
For LTR override: wouldn't Bidi_Mirroring bring exactly the expected
