Thanks to you both. (The workaround of forcing an explicit dir
node at the beginning of the paragraph seems to work, too, with
FreeSerif, Amiri, which also had misplaced kerns, etc.)

This means I can typeset Arabic documents without having to
patch almost every macro where directionality is relevant (quite
a lot), and without having to mark explicitly chunks of L text.
