AFAICT prog-widen doesn't look at the PREVIOUS-CHUNK part of
prog-indentation-context.
So PREVIOUS-CHUNK only exists in the docstring of
prog-indentation-context and nowhere else.

How do you propose we detect when MMM is active?


        Stefan "and by the way, those widen calls are beneficial even
                when MMM is not active, but if you insist I'm OK
                delaying this side benefit to Emacs-27"
