It's not a user-level option.  Set it like this:

 M-: (setq bidi-display-reordering t) RET

Aha, that's better.

??? If you move the cursor through the Arabic characters, doesn't it
move right to left?  I definitely see the order of the characters
change when I toggle bidi-display-reordering on and off.

Ok, using the "Middle/Near East" line near the top of the display, C-f seems to work properly; after the space following the colon it jumps to the right-most Hebrew char, after which C-f steps to the left.

The problem is that the char display of the Arabic is still left-to-right.  That is, C-f steps through the run RTL, but the reading order is still LTR  (i.e. like this:   ALSLAM @LYLM; it should be MLY@ MALSLA)

What "bzr merge"?  Are you using the current trunk or something else?

bazaar command?  If memory serves, I followed the instructions at https://savannah.gnu.org/bzr/?group=emacs.  I'm not familiar with bazaar so "bzr merge" was my best guess as to how to pull in the latest changes; seemed to work, is there a better way?

M-x report-emacs-bug RET, but please before that ask on emacs-devel,
perhaps some other OS X users can help you.  I don't see any of these
problems.

I'm thinking more along the lines of a place to keep notes, comments, etc. organized  - stuff that may or may not be a bug, that may or may not merit documentation, etc.  Stuff tends to get lost in mailing lists.  Actually, I have a wiki so maybe the thing to do is keep my notes there and submit items to this list as needed.  See http://wiki.sibawayhi.org/ (and please take the rhetorical outbursts with a grain of salt ;).

Thanks
