The standard GNU Emacs "narrow-to-region" and "widen" allow
for only one-or-none narrowing - i.e. you're narrowed or
not.

Often I would have found it helpful to have recursive
narrowing.  Is there any way to do this?

(An example: when I'm already narrowed to a particular
function in a source program, I would like to restrict
further to a particular part of that function for some
operation, and when I am finished I'd like "widen" to undo
just the top level restriction, leaving me still narrowed to
the whole function).
