title: ckeditor removes new line characters from source
body: <p>Using CKEditor 4.9.2 on a <code>textarea</code>, which already has content, separated by new lines (<code>\r\n</code>). When the CKEditor instance loaded, these new lines were removed like this:</p>
  
  <p><a href="https://i.stack.imgur.com/70CTR.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/70CTR.jpg" alt="New lines removed"></a></p>
  
  <pre><code>&lt;textarea name="message" &gt;
  row 1 text text text 
  row 2 text text text text text text 
  row 3 text text 
  row 4 text 
  row 5
  &lt;/textarea&gt;
  </code></pre>
  
  <p>I can't convert them to <code>&lt;br&gt;</code> tags, have to work with <code>\r\n</code> characters.</p>
  
  <p>How can I keep the <code>\r\n</code> characters?</p>
