Hm.  This is all pretty new to me...  but...
overlay-arrow-variable-list is a list of variables, each of which can
have one single position.

So to have more than a single fringe indication, we'd have to generate
one variable per breakpoint?

And you can't just put the positions into the list, either:

(setq overlay-arrow-variable-list
      (list (set-marker (make-marker) (point-min))
            (set-marker (make-marker) 100)))

Am I missing something, or does this mechanism just not support an
arbitrary number of fringe indicators?  (Well, without generating
variables dynamically, which I'm guessing we don't want to.)
