title: application.css.scss not compiled on Rails 4
body: <p>I felt strange that why the style not loaded,</p>
  
  <p>So I wrote wrong content intentionally on <code>application.css.scss</code>,</p>
  
  <p>And <code>precompile</code> and load the page didn't give me any error.</p>
  
  <p>I thought the <code>application.css.scss</code> file must not be loaded and compiled.</p>
  
  <p>Unfortunately, it seems no to be.</p>

   * This is a manifest file that'll be compiled into application.css, which will include all the files
   * listed below.
   *
   * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
   * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
   *
   * You're free to add application-wide styles to this file and they'll appear at the top of the
   * compiled file, but it's generally better to create a new file per style scope.
