All,

Pardon for trying to boost the topic, but I still can't seem to gain
control over marginal material in an Arabic section using the new
typo-mar.mkiv. I confess, it's quite likely that I'm just not getting
something obvious.

I've rotated the page to landscape to show where the marginal material
winds up when margin is [right]. When it's [left], it overwrites the
beginning of the Arabic line

If anyone has thoughts on this, I'd be grateful.
