[I suspect that the following is not what Mark has in mind, and if so then I
don't want to divert attention from his questions - I'll drop it (or start a
different thread if there is any interest).]
One thing I've sometimes thought would be handy is an additional widening
command, `widen-one-level', which would widen only as far as the next-to-last
narrowing.
You can narrow and then narrow further, any number of times. But `widen' always
widens completely. Sometimes I would like to just undo the last level of
narrowing, returning to the previous level (or to the top level, if there is
only one narrowing).
This would require managing a list or stack of narrowing limits etc.
I have no idea whether anyone else would find such a command useful. And I can't
really characterize useful use cases. But I know I've sometimes wanted such a
feature.
