Hi,

there seems to be a problem handling 'display' text property in
bidi. The bug can be reproduced with this:

  (progn
    (switch-to-buffer "*tmp*")
    (setq bidi-display-reordering t)
    (insert "first\nsecond\n" (propertize "III" 'display "third") "\nfourth"))

After evaluating the form the buffer looks like this:
('|' represents the cursor):

-------------
first
second
third
II
fourth|
-------------

The extra line showing "II" disappears when disabling bidi.

That's right: `display' properties were not yet made bidi-aware.  It's
on my TODO list.  Patches welcome to fix it.

Thanks.
