That is interesting. Thanks. But considering this, we're unlikely to
have `Info-mode' as a submode somewhere.

If widen-function is technically feasible, I'd rather go in this
direction rather than introduce a variable everyone can ignore.

That is true. However, as long as we don't have solutions for the hard
problems in the multiple-mode space, we might as well hold of on making
the change that only solves the relatively easy one (and let
multiple-mode solutions use `widen' for the time being).
It doesn't seem to me like it moves toward solutions for the hard
problems, in any way.

Do you have a submode in mind that will benefit from this distinction
(external vs internal narrowing) in practice, right now?
