    I believe this displays correctly if the base directionality of the lines is RTL. (Evidently, none of this software tries to guess base directionality using the first strongly directional character of the line.) I'm sending this email as an RTL document, and it corrects the comma problem on my screen.


    P.S. Of course, there are few other problems for the LTR stuff (like where the punctuation ends up at the end of the line).
