> 2.1) This exposed three bugs in the bidi rendering of the diary buffer:
> 
>     A) Hebrew text lines in the diary are rendered left justified.
> 
>     B) Hebrew text lines in the diary are rendered in reverse sequence.
> 
>     C) RTL and LTR lines are rendered out of sequence to each other.
> 
> 2.1.1) Bug A can be avoided by locally redefining the regexes that
>        identify bidi paragraphs, and I've included that in the attached
>        code.
> 
> 2.1.2) Bugs B and C may possibly be related to bug #15541.

I'm interested to understand better these problems.  Please give
detailed instructions for how to reproduce them with your calendar
code, or show a screenshot, because I don't think I understand well
enough from the above description what the display looks like.

Thanks.
