title: Running remote commands after vagrant ssh
body: <p><code>vagrant ssh -- EXTRA SSH ARGS</code> is supposed to allow extra args to be passed to ssh. </p>
  
  <p><code>vagrant ssh -- -t 'cd /var/www'</code> should ssh into vagrant and change directory to <code>/var/www</code>, but doesn't. Instead it returns</p>
  
  <blockquote>
    <p>ssh: Could not resolve hostname ls: nodename nor servname provided, or not known</p>
  </blockquote>
  
  <p>What am I missing?</p>
