I found a typo in the LuaTeX manual. It would be nice if this error
could be corrected.

I've attached a patch. I made this patch from the mirrored repository on
Github (https://github.com/TeX-Live/luatex).
Despite an intensive search I could not find the current development
repository of LuaTeX. I read about an upcoming Git migration in the mail
archive. Is there any progress?
