title: {% spaceless %} tag for Jinja templates?
body: <p>Django has a useful <code>{% spaceless %}</code> tag that strips extra whitespace from HTML.</p>
  
  <p>My templates are producing a lot of whitespace and it's too much of a pain to add the <code>{%-</code> and <code>-%}</code> everywhere to do whitespace control. Has anyone seen a filter like <code>{% spaceless %}</code> for Jinja, or maybe <code>{% htmltidy %}</code>, so that I could view clean HTML while developing?</p>
