title: How to add an '--' option in upstart exec
body: <p>I've been using redis-commander but now I need to start it automatically on boot up.
  I used upstart to make this happen but problem is it ignores the "--" option. I'm doing it like this.</p>
  
  <pre><code>script
      exec /usr/local/bin/redis-commander --redis-password M+4IZ3hZy7/cf7
  end script
  </code></pre>
  
  <p>Seems like it ignores the --redis-password options since I got this error</p>
