title: Remove unnecessary whitespace from Jinja rendered template
body: <p>I'm using <code>curl</code> to watch the output of my web app.</p>
  <p>When Flask and Jinja render templates, there's a lot of unnecessary white space in the output.<br />
  It seems to be added by rendering various components from Flask-WTF and Flask-Bootstrap.</p>
  <p>I could strip this using <code>sed</code>, but is there a way to control this from Jinja?</p>
