emacs -Q
The following lines are to be typed in the resulting *scratch* buffer:
M-x toggle-truncate-lines RET
(setq bidi-display-reordering t) C-j
C-u 82 a
C-a
The cursor will move not to the last "a" on the line, but rather to the
newline of the first line in the window. At this point C-f and C-b can
cause some strange behavior.

It's a cursor-positioning problem (see "C-x ="). I will take a look
when I have time. C-b does work correctly, though.
Thanks.

Please try with the latest trunk, and if you still see some problems,
feel free to reopen this bug (or file a new one if something else
