title: vim-fugitive automatically gdiff on enter from gstatus
body: <p>When using vim-fugitive if you issue <code>:Gstatus</code> it splits the screen and gives you the would be git commit editor and you can move over different files that have changes and press enter to see them in the other half of the screen. I believe it is like issuing <code>:Gedit</code> .          </p>
  
  <p>I then need to issue a <code>:Gdiff</code> manually to split the editor in half and see the side by side diff of the file to review and or stage it.</p>
  
  <p><strong>My question is</strong> is there a way to make it automatically go to <code>:Gdiff</code> when I press enter, while my cursor is on a file name that has changes.    </p>
  
  <p>Basically trying to save some time when going through a large list of files. </p>
