Category problems again
Fragment of a discussion from User talk:Rua
aus-wem shouldn't exist in the module (and doesn't exist any longer in the template namespace). As for whether to use a hyphen or a space: I changed xww to use a hyphen, so I must have looked into it and found that it was more commonly hyphenated than not, as part of my long-term effort to ensure Wiktionary calls each language by its most common distinct English name (or makes exceptions consciously, rather than by bot-copypasting SIL errors).
