title: Add a link to a label/hint in formtastic with haml
body: <p>I'm trying to add a link to a checkbox in formtastic, using haml. It looks like formtastic removes all ruby/haml/html syntax from the text for the label or hint when it parses it. </p>
  
  <p>That is, this doesn't work: </p>
  
  <pre><code>= f.input :terms, label: '=link_to \'Here\', path_to_link', hint: '=link_to \'Other Place\', path_to_other_link', as: :boolean
  </code></pre>
  
  <p>Is there anything that will other than writing another div outside of this input? Or am I going about this all wrong? I'm a rails/haml/formtastic noob. </p>
