You could just as well use "german" instead (I wasn't paying
attention), but do you want to say that "ngerman" works in lualatex,
but not in plain luatex? Since that would be weird.

Also, I didn't manage to reproduce the behaviour in plain luatex
earlier, but I think that I understand now why this was the case.

Thanks a lot. This rings a bell. I was trying hard to find the
original email (probably discussed by me, Jonathan Kew and others,
probably on xetex mailing list, but maybe privately), but without any
success. Anyhow ... does the following code from xelatex.ini ring a
bell to anyone else?

It sounds like a bit more work to do for Manuel :)
