title: Why does Ruby on Rails generate add a blank line to the end of a file?
body: <p>Running <code>rails generate controller Foo home</code> results in:</p>
  
  <pre><code>class FooController &lt; Application Controller
    def home
    end
  end
  (There's nothing on this line in the actual file, just a blank line)
  </code></pre>
  
  <p>Is there a purpose to this blank line?</p>
