bug#31240: 26.1; mouse-save-then-kill does not kill rectangles

[martin rudalics]

Looking again at this part

+          (line (progn
+                  (forward-line 0)
+                  (count-lines (point-min) position))))

I now ask myself why you need to go to the beginning of the line at
all.  'count-lines' doesn't care about the actual position of point.
So you either have to do

                  (count-lines (point-min) (point))

or just do

                  (count-lines (point-min) position)

without going to the beginning of the line because POSITION and the
position at the beginning of its line should be on the same line.

Great.
