Usually this worked correctly due to the fact that directory buffers
were sufficiently high.  But for `pop-up-frames' non-nil addicts this
was not necessarily the right behavior.

Anyway, I suppose you mean something like

(defun dired-pop-to-buffer (buf)
  (let* ((split-height-threshold 8)
	 split-width-threshold
	 (buffer (get-buffer-create buf))
	 (window (window--try-to-split-window (selected-window))))
    (if window
	(progn
	  (select-window window)
	  (set-window-buffer window buffer))
      (pop-to-buffer buffer))
    (when dired-shrink-to-fit
      (fit-window-to-buffer nil nil 1))))

Would the above code handle that?
