I would be VERY surprised if M-0 M-r suddenly started to scroll the
window.

Since move-to-window-line moves _point_ in the current window _without_
scrolling, I don't understand why it would ever consider scroll-margin.

But of course, the strict interpretation of scroll-margin's doc string
says that point may never occur in these margins.  I think that is too
restrictive.
