Many of the fringe indicators are very dynamic, and only known in
relation to a particular redisplay. Morever, the presence of the fringe
can change the physical dimensions of the area available for redisplay.
If there's a particular less-dynamic indicator you're interested in,
then perhaps it reflects a condition that can be tested for more easily
in lisp code.
