doc: /* Split WINDOW, putting SIZE lines in the first of the pair.
WINDOW defaults to selected one and SIZE to half its size.
-If optional third arg HORFLAG is non-nil, split side by side
-and put SIZE columns in the first of the pair. In that case,
-SIZE includes that window's scroll bar, or the divider column to its right.
+If optional third arg HORIZONTAL is non-nil, split side by side and put
+SIZE columns in the first of the pair. In that case, SIZE includes that

Interactively, all arguments are nil.

Returns the newly created window (which is the lower or rightmost one).
The upper or leftmost window is the original one, and remains selected
