Here is a possible doc string for the renamed `rectangle-pos-cols':

"Return cons (START-COLUMN . END-COLUMN) of columns delimiting a rectangle.
START and END are buffer positions of the rectangle corners.

Optional argument WINDOW is the window displaying the rectangle.
It defaults to the selected window."

I'm not sure it is accurate, but I think so.  (I'm no expert on this.)
