title: What does "CL" mean in a commit message? What does it stand for?
body: <p>From Angular.js change log:</p>
  
  <blockquote>
    <p>... After this CL, ng-trim no longer affects input[type=password], and will never trim the password value.</p>
  </blockquote>
  
  <p>This is from one of the commit messages, so presumably it means the patch. What does it stand for? Change log? </p>
