>      Split WINDOW-TO-SPLIT into two windows, one above the other.
>    WINDOW-TO-SPLIT defaults to the selected window if omitted or nil.
>    The newly created window will be below WINDOW-TO-SPLIT and will show
>    the same buffer as WINDOW-TO-SPLIT, if it is a live window, else the
>    buffer shown in the WINDOW-TO-SPLIT's frame's selected window.
