Likely just an oversight, but it seems if  is used, the fallback language code is returned rather than the message from the fallback language.

Regarding a wgContentLanguage fallback: the use case for it is fairly specific (a logged-in Russian (or anything but English) user visiting a wiki that isn't Russian or English), so I suppose it would depend whether the wiki's language or English is the more desirable fallback. What language does MediaWiki use in such a situation?
