title: Closing multiple issues in Github with a commit message
body: <p>I know you can close issues by putting <code>closes #1</code> or <code>fixes #1</code> in the commit message. What is the best way to close multiple issues in the same commit message?</p>
  
  <p>Also, it appears that using <code>fixes</code> rather than <code>closes</code> doesn't create a link from the commit message to the issue, but it <em>does</em> close the issue. What's up with that?</p>
