Ok, we have introduced a new variable.  So far it is used nowhere in
Emacs, and it's said to not turn it on by default.  Nothing has actually
changed.  The recipe I had posted behaves the same.  Do I miss
something?

BTW, did you ever use folding?  I think not as often as I do, else you
would have known the issue we are talking about.  My feedback was not
meant to annoy you - I wanted to share my experience as a user.  Didn't
know that that's irrelevant.

I don't even know what to respond to that.
