title: link_to root appears empty
body: <p>In rails when using:</p>
  
  <pre><code>&lt;h1&gt;&lt;% link_to "Home", root_url %&gt;&lt;/h1&gt;
  </code></pre>
  
  <p>Nothing appears inside the  tags. My routes.rb is:</p>
  
  <pre><code>MyApp::Application.routes.draw do
    root :to =&gt; 'posts#index'
    resources :posts
    match "/help" =&gt; "help#index"
  end
  </code></pre>
