Right, so let's forget about latex's tabular in the rest of the
discussion. Patching the executable for this reason is even worse
than having to patch the latex source code.
IMHO (and bear in mind that I do not know anything about arabic math
typesetting) I think Khaled is right: it would make considerably
more sense for all \hboxes to always use the current \textdir unless
instructed otherwise. \hboxes in vertical mode currently inherit
\bodydir, which I think is even weirder perhaps.
