title: git review not working-change id issue
body: <p>I have committed few files and trying git review command.
  But it is throwing following error.</p>
  
  <pre><code>2016-08-10 04:44:26: Commit message must have exactly 1 change-id.
  2016-08-10 04:44:26: Commit message validation failed.
  </code></pre>
  
  <p>Commit message is already  having the change id at the bottom of the message. Still it is throwing error. I am using "git review" command. Please usggest some solution.</p>
