UKenglish or USenglish and \foreign* environments

[jspitz]

csquotes lowercases all language names in \csq@lang etc. with the rationale "workaround for page headers of book.cls et al." (see comment in csquotes.sty). This results in language names that have uppercase letters (UKenglish and USenglish) not being detected (the lowercase variants, ukenglish and usenglish, are unknown to babel).

I think this is not a big issue, since people can use british and american instead, but it should be documented.

I have posted a possible solution to the problem.

Fixed via #37.

That plan won't work: we need an expandable solution. I will do that using expl3, but it will need to wait for the 2020-02-02 kernel release.

OK. Sorry, I should have checked more carefully.
