title: Where does git store the commit message
body: <p>I was doing a commit and noticed I had made a mistake.  Since closing nano would commit the change, I force-closed the terminal.  This left the .swp file somewhere, preventing me to commit in the future:</p>
  
  <pre><code>*** Error in `nano': malloc(): memory corruption (fast): 0x000000000204a990 ***
  error: nano died of signal 6
  error: There was a problem with the editor 'nano'.
  Please supply the message using either -m or -F option.
  </code></pre>
