If this option is non-@code{nil}, the scroll functions move point so
that the vertical position of the cursor is unchanged, when that is
possible.
If this option is @code{t}, scrolling which would move the current

If it is non-@code{nil} and not @code{t}, then the scrolling functions
always preserve the vertical position of point, if possible.
