Thanks.  The following case looks a bit problematic here.  Suppose my
rectangle in an Elisp buffer is

;;;;;;;;;;;;;;;;;;;
;;;;;;RECT;;;;;;;;;
;;;;;;RECT;;;;;;;;;
;;;;;;RECT;;;;;;;;;
;;;;;;RECT;;;;;;;;;
;;;;;;RECT;;;;;;;;;
;;;;;;;;;;;;;;;;;;;

If I now drag it up by one line and four columns to the right (so that
it just does not intersect with itself) I get

;;;;;;;;;;RECT;;;;;;;;;
;;;;;;RECT;;;;;;;;;
;;;;;;RECT;;;;;;;;;
;;;;;;RECT;;;;;;;;;
;;;;;;RECT;;;;;;;;;
;;;;;;;;;;;;;;;
;;;;;;;;;;;;;;;;;;;

which is somehow counterintuitive.  Any ideas?

Thanks, martin
