title: dired mode single window? (emacs)
body: <p>is there a way to have dired operate in a single window so that when I traverse through directories I don't have n number of dired buffers for the intermediate directories? However - if I start another dired buffer in a completely separate directory (from the minibuffer rather than hitting [enter] on a subdirectory in an already open dired instance) I'd like to retain the two separate dired buffers... I guess I'm using ido-dired since I have ido-mode on but I don't know that the solution would be different? Thanks much!</p>
