Steps to reproduce:

echo -n foo > /tmp/foo1
echo bar > /tmp/foo2

LANGUAGE=de_DE src/emacs -Q /tmp/di.el

(ediff-files "/tmp/foo1" "/tmp/foo2")

Result:

Well, we obviously can't add all the languages in the world to
`ediff-diff-ok-lines-regexp', but we can run diff in a known
environment.

Any comments?  Is this the best way to do this sort of stuff?  The
LOCALE/LANGUAGE/LC_* variables can be kinda confusing.
