That's a good data point, but since I don't understand why anybody would 
make (or does make) case-fold-search buffer-local, I'm not going to 
hurry to fix those cases.

That sounds attractive (ignoring all buffer-locals when let-bound?), but 
I'm guessing there are enough valid use cases for this behavior.
