title: Rails Path Helper for Root should output "/"
body: <p>In my routes file, I have a resource called products. The index action of the products resource is also my root path.</p>
  
  <pre><code>resources :products
  root :to =&gt; "products#index"
  </code></pre>
  
  <p>When I use the helper method products_path (in a redirect or link), it returns "/products". But what I want is for it to return "/".  I know it's the same page, but I want to keep my URL's consistent.</p>
  
  <p>How can I fix this?</p>
  
  <p>Thanks!</p>
