Except that the LC_MESSAGES catalog may include messages such as "blah
%d blah" that get translated for use as a printf argument, and the lack
of matching LC_NUMERIC will make the translation look wrong.
Translators often assume that their translation is being used with
everything else about the locale matching the locale of the translation.
