What could the Lisp programmer do in this situation?

Only for some of the 'format's capabilities, not for all of them.

I don't think it's TRT for Emacs to expose locale-dependent features
that cannot be controlled from Lisp, sorry.  We need to find a better
way.  For example, there could be a Lisp variable that specifies the
group separator character, and then 'format' could use that character
when the format spec includes %'.  Which means we'd need to implement
that in our own code; patches welcome.
