There are various ways to do things very similar to what posn-set-point
does, so a hook on this function seems rather odd to me: it will only
catch some window selections and some point movements.

IOW I find it difficult to characterize when these hooks will be run

(except with the trivial characterization that they're run when

posn-set-point is run, which is not very meaningful since no command is

documented to use this function).

​FYI, the initial desire for these hooks came from wanting to do something whenever the mouse set point.

Then I thought it would be more useful if it covered any interactive setting of point, which led to posn-set-point

(called by mouse-set-point).  If there are better ways to do this, let's discuss them.
