Before those directional fixes the value of bidi-paragraph-direction
was 'left-to-right', i.e. it ignored the dir=rtl meta-data.  So
obviously, the problem didn't exist back then, but it didn't start
_because_ of that change.  It's just that the change you made exposed
a bug in the line-breaking algorithm -- it somehow assumes
unidirectional text somewhere.  If you manually set
bidi-paragraph-direction to 'left-to-right', after visiting that file,
the problem disappears, leaving on screen just the incorrect display.

If you can point me to the code which does that, I might find the
problem and suggest the solution.

Thanks.
