There is a real problem here: currently font-lock will widen right back.
There might be a few more cases where widening will happen currently,
but I think font-lock is the main one.  IMO we should specifically fix
those few cases we encounter, rather than add to the narrowing
complexity (which tends to encourage major modes to widen since they
basically can never know why a narrowing is in effect) by imposing a
"locked narrowing".
