Here is a simple patch that aims to bring mg's behaviour closer to
emacs.

emacs dirname

Will open `dirname' in a dired-buffer. This patch aims to do the
same. Allas I got stuck. If one presses return you get the c-n
effect instead of opening the file under the cursor. I don't
really understand why actually. So if anyone thinks this is a
useful feature and knows how to make it work properly, be my
guest.
