`dired-pop-to-buffer' is no longer called and `dired-shrink-to-fit' is
no longer consulted.  You have to enable `temp-buffer-resize-mode'.  If
you really insist on handling dired's pop-up buffers separately, I can
do that by binding `temp-buffer-resize-mode' appropriately, but I'd
rather have a common solution for handling all temporary windows in the
same manner.
