Point is moved to the first visible line in the window instead of
remaining at the next-to-last line.

If you do this anywhere else in the buffer (except the last two lines
(and the first two lines)), the visual point is kept the same place.

I don't use this setting myself, so I'm wondering -- is this intended
behaviour (i.e., sorta not using the setting on the two first/last
lines), or is this a bug?
