Yet if I remove `exchange-point-and-mark', the command does not
work any longer.  Please compare the effects of the following
command:

(defun yank-and-mark/rr (&optional $arg)
  (interactive "*P")
  (yank $arg)
  (exchange-point-and-mark)
  (setq deactivate-mark nil))

with the same command, but without `exchange-point-and-mark'.

Tested in the "*scratch*" buffer, after "emacs -Q".  In
Fundamental Mode, too.
