OK. which-function works by trying out a whole series of functions and
returning the first result which is non-nil. CC Mode is now returning a
non-nil value (namely "class Foo") for one of these functions where it
previously didn't.
There're things like backward compatibility (with what exactly, I'm not
sure) to take into account before changing things here.
I'll look more closely into this in the coming days.
