I understand now what exactly is annoying about the current behavior:
when there is already 2 or more windows on the frame, after splitting the
selected window, you create a new window that displays the same buffer, then
you decide you need to undo the recent split, and the quickest way to do this
is to delete the selected window with 'C-x 0'.  After that, the window
configuration looks exactly as before the split, with only one difference -
the cursor jumps to an unrelated window.
