title: Git problem with interactive rebase
body: <p>This is basically what happens:</p>
  
  <pre><code>&gt; git rebase -i HEAD~3
  Successfully rebased and updated refs/heads/master.
  </code></pre>
  
  <p>Pops open my text editor then immediately "completes" the rebase before I even have the chance to do anything. Anyone know what might be causing this?</p>
  
  <p>I'm using msysgit on Windows 7: git version 1.7.3.1.msysgit.0</p>
