title: heroku config:push not adding environment variables
body: <p>Hi I have done the following from the <a href="https://devcenter.heroku.com/articles/config-vars" rel="nofollow noreferrer">heroku tutorial</a>.</p>
  
  <pre><code> heroku plugins:install git://github.com/ddollar/heroku-config.git
   heroku config:push --overwrite
  </code></pre>
  
  <p>my <code>.env</code> file is in root of project directory </p>
  
  <pre><code>GOOGLE_RETURN_URL = http://example.herokuapp.com/auth/google/return
  GOOGLE_REALM = http://example.herokuapp.com/
  </code></pre>
  
  <p>I also set the --overwrite flag as <a href="https://stackoverflow.com/questions/14016273/heroku-configpush-not-updating-environment-variables">this answer suggested</a></p>
  
  <p>however when I echo my <code>heroku config</code> it remains empty!</p>
