[luatex] bug in RTL typesetting?

[وفا خلیقی]

Thanks Khaled. I do not know Lua and just started to learn it. I think macro
programming is an art.. In xepersian, I only had four primitives for
directions \beginR, \endR, \beginL, \endL, and I managed everything to work
properly except colours which I did not find any way to fix that.


But offcourse in some situations macro programming gets quite complicated
and so knowing lua will help heaps.
