title: MacVim :e expands to Edit, and Edit! won't let me discard changes?
body: <p>When I type :e, MacVim automatically expands this to :Edit. The problem with this is that I can't discard my current buffer with :Edit!, because I get an error message saying that "!" isn't allowed.</p>
  
  <p>I have two questions:</p>
  
  <ol>
  <li>Why does :edit! work and not :Edit!</li>
  <li>Is there a way to disable this auto-expand feature in MacVim, or perhaps switch it to expand to :edit! and not :Edit! ?</li>
  </ol>
  
  <p>Thanks!</p>
