I thought about it some more.

We have a notion of mark that is somewhat overloaded. On the one hand,
there is the mark ring and the global mark ring whose purpose in life
is to help the user navigate back to positions they visited earlier.
On the other hand, the mark is used as one of the two delimiters of
the region.

It seems to me these two uses of the mark are mutually disjoint, and
it might be a better model if they were decoupled.
