Oh, there was another typo. I did not test that the documentation
is typesetting properly, and there was a "\begn{macro}" instead
of `\begin{macro}`. I also updated the checksum of preview.dtx.
Tested now with the various engines and things seems to be working
(but please test thoroughly :)

Just sent an email, but in case it is suffice, when I'll get an answer
I'll attach the assignment. BTW, it is not that important, but
why is my postal address needed?

Subject: [PATCH] consider pagerightoffset in luatex with rtl languages
This patch will calculate \pagerightoffset when LuaTeX is used
and the page direction is right to left. It is important as in
this case LuaTeX will use this register, and not \hoffset to
position the page.
