This must be a new and exciting definition of simply that I am
not previously aware of.  Else I'm being particularly dense.

Glancing through the source, this seems like it would be a pretty
major change.  I guess BEGV and ZV would have to be changed from
buffer positions to lists of buffer positions.  Then everything
that looked at them would be updated to respect this change.  And
so forth.  Or do I have the wrong end of the stick?
