I tend to think the answer should be:

* If the language is "auto", then use each frame's language; otherwise
* If the user specified a particular language, use that language for
  everything.

That would be good to have but I don't think it ought to be tied to this
particular project.  Certainly plenty of other code already just sets
and resets the global.
