title: Disable formatting in Twig
body: <p>In my Twig template comes variable <em>source</em>, which contains whatever source eg. php, js, html ... etc.
  Source is formatted - with whitespaces and /r/n, but Twig renders it all in one line. I tried next:</p>
  
  <pre><code>{% autoescape false %}
  {{ source }}
  {% endautoescape %}
  </code></pre>
  
  <p>and</p>
  
  <pre><code>{% autoescape false %}
  {{ source|raw }}
  {% endautoescape %}
  </code></pre>
  
  <p>but didn't managed to success.
  Here is output of <code>{{ dump(source) }}</code>:</p>
  
  <pre><code>string '$builder-&gt;add('availability', 'choice', array(
      'choices'   =&gt; array(
          'morning'   =&gt; 'Morning',
          'afternoon' =&gt; 'Afternoon',
          'evening'   =&gt; 'Evening',
      ),
      'multiple'  =&gt; true,
  ));' (length=219)
  </code></pre>
