This might be good for post-23.1, but the reported annoyance is still here,
so we need just to restore the old 22.1 behavior of `dired-pop-to-buffer'.

Martin, do you think this is possible without reverting `dired-pop-to-buffer'
to pre-December 2008 state, and making necessary changes in window.el
thus providing the same behavior that was in `dired-pop-to-buffer'?
