Don't see why info couldn't care for that - for example by indexing 
previous narrowing and re-narrow following widen if appropriate.

May think of nested narrows that way, which wouldn't require changes of 
Emacs core.

But info seems a special case anyway, while a true multi-mode really 
being at stake. Instead of diving into info now, suggest to continue 
with a multi-mode issue.
