But then we have to care about the position of each window's point as
well.  Consider the case of a vertical combination of three windows
with all windows' points at their top.  Deleting the middle window
should then probably select the lower window.  With all points at
their windows' bottoms we probably should select the upper window.

Obviously, these C-x o are needed to make the example work.  Without
them the window split off by C-x 2 would be selected.

We can add an option for that.  How should we call it?
