Thanks, installed (after changing text-property-any with
text-property-not-all so we also detect non-t non-nil values as meaning
"read-only").

AFAICT the next step is to introduce a function `reactivate-mark`.
This function will need to know what kind of mark was earlier activated,
so we will need to store the "kind of mark" somewhere.
I guess the easiest is to introduce a new var
`reactivate-mark-function` (so reactivate-mark doesn't need to do much
more than funcall it).

Then we'll want to change a few places in Elisp to set/reset this var.
