title: Multiline Search and Replace in Atom editor
body: <p>I want to find this: </p>
  
  <pre><code>&lt;p&gt;
  various text and code
  &lt;/p&gt;
  </code></pre>
  
  <p>...and replace it with completely different text. Atom doesn't seem to have a multi-line RegEx flag. How can I accomplish this?</p>
