[luatex] loading hyphenation list by luatex-hyphen

[Herbert Voss]

Hi all,

I have

\documentclass{minimal}
\usepackage[french,english,ngerman]{babel}
\begin{document}
foo
\foreignlanguage{french}{bar}
\foreignlanguage{english}{baz}
\end{document}

with a log of (important is the last line)

-----------------start --------------------
[...]

I created a file with the hyphenations exception
hyph-de-1996.hyp.txt in
/texlive/2012/texmf-dist/tex/generic/hyph-utf8/patterns/txt
which was before already there but empty.

Why is that file not taken into account by luatex-hyphen?
In the language.dat.lua I have

	['ngerman-x-2012-05-30'] = {
		loader = 'dehyphn-x-2012-05-30.tex',
		lefthyphenmin = 2,
		righthyphenmin = 2,
		synonyms = { 'ngerman-x-latest' },
		patterns = 'hyph-de-1996.pat.txt',
		hyphenation = 'hyph-de-1996.hyp.txt',
	},


luatex 0.72 with xurrent texlive
