"Called for effect" warning in ispell.el

[Juanma Barranquero]

In `ispell-show-choices' (lisp/texmodes/ispell.el), `get-buffer-window'
is called for effect somehow, or an oversight?

(defun ispell-show-choices (line end)
  "Shows the choices in another buffer or frame."
  (if (and ispell-use-framepop-p (fboundp 'framepop-display-buffer))
      (progn
        (framepop-display-buffer (get-buffer ispell-choices-buffer))
        (get-buffer-window ispell-choices-buffer t)            ;;*****
        (select-window (previous-window))) ; *Choices* window
