title: Rails 3 and devise escaping mailer templates
body: <p>I'm using rails 3 and devise for authentication.</p>
  
  <p>Translating my mailer templates to anything but the devise default results in html escaping. A particular consequence of this is the confirmation of new account email includes an invalid confirmation token.</p>
  
  <pre><code>&lt;p&gt;&lt;a href=3D"http://localhost:3000/users/confirmation?confirmation_token=
  =3D88uo7jetcetc"&gt;Confirma=
  r mi cuenta&lt;/a&gt;&lt;/p&gt;
  </code></pre>
  
  <p>The preceding 3d is html escaping and should not be there. Using raw and html_safe has no consequence on the output.</p>
