title: Emacs Dired Behavior
body: <p>I have used emacs for years and am accustomed to having emacs open a selected file in the same window that dired is executed in.  In recent revisions, when dired is executed  with say 2 windows open, the file selected will be displayed in the alternate window from dired.  How can I set up emacs to use the same window to display the file as died (allowing me to look at two files simultaneously--the way emacs used to work)?</p>
