Are you also thinking of addressing the command-line in terminal emulators
that have Bidi support. I'm talking about the case where one wants to do
grep "ARABIC-3 ARABIC-2 ARABIC-1" filename
note here that bidi needs to kick-in for proper display (the numbers above
denote word entry count) as well as
diff FILENAME-1 FILENAME-2
and in this case bidi was not supposed to have been engaged since order
does matter to convey proper context.
NOTE: All caps are non-latin bidi-required characters.
It would be ideal to find a mechanism that would not involve the use of
directional markers (ie. to add-in the proper smarts needed in bash for
it to denote proper context - when within quotes apply bidi else don't
among other things -- well maybe not bash per se, but a library call is
needed for automatic direction setting).
