The struct bidi_it has a pointer to a window.  I think something needs
to be done about that.  I didn't know what, so I made a note "for
later".  I don't see the string you're talking about but I don't
actually understand what this code does.  I just looked at the types.

Then maybe a comment would be appropriate.  Usually, any root needs to
be traced.
