title: Emacs comment-region in C mode
body: <p>In GNU Emacs, is there a good way to change the comment-region command in C mode from</p>
  
  <pre><code>/* This is a comment which extends  */
  /* over more than one line in C. */
  </code></pre>
  
  <p>to</p>
  
  <pre><code>/* This is a comment which extends
     over more than one line in C. */
  </code></pre>
  
  <p>? I have tried</p>
  
  <pre><code>(setq comment-multi-line t)
  </code></pre>
  
  <p>but this does not help. There is a <a href="http://www.gnu.org/software/emacs/manual/html_mono/emacs.html#Multi_002dLine-Comments" rel="noreferrer">section on multi-line comments in the Emacs manual</a>, but it does not mention anything.</p>
