That is indeed what I meant (and I even wrote boolean instead of int
early on), but then thought that this option ought to be expandable
just in case (for any potential bug work-arounds, application issues,
etc -- no harm done, use this 'int' as a 1/0 and/or TRUE/FALSE :-)

OK - I'll keep checking the release announcements for it.

Sorry I wasn't able to find any info on FriBidiEnv (haven't looked into CVS,
which is where I think it is), but if that is an environmental variable that
a user ought to set, I would still suggest implementing a function variable
as is noted above (ie. the NEW part above) to give the application ultimate
control.  If its a struct, on the other hand, that's encompassed/controlled
internally then great (the "Env" part threw me for a loop).

BTW: please don't forget to CC those included.
