That seems to go in the right direction, yes.

Exactly (tho the name should clarify that we're talking about something
related to the mark).

I think it should be the object stored in `mark-active`.

We might be able to merge reactivate-mark and activate-mark into
a single mark-activate (and use the "mark-" prefix in all other methods)
which by default just does (setq mark-active <thearg>).

I don't understand the question: when would we st it back (to t or to
some saved value)?
