title: Append *multiple* paths to PYTHONPATH in fish
body: <p><a href="https://stackoverflow.com/questions/24308310/how-can-i-set-pythonpath-in-fish">Here</a> I read how to append to PYTHONPATH in fish, and that works fine for one string.</p>
  
  <p>However, if I do this:</p>
  
  <p><code>set --export PYTHONPATH $PYTHONPATH path1 path2</code></p>
  
  <p>I get this:</p>
  
  <pre><code>&gt;&gt; import os
  &gt;&gt; os.environ["PYTHONPATH"]
  'path1\x1epath2'
  </code></pre>
  
  <p>Alternatively:</p>
  
  <pre><code>$ python -c "import os; print os.environ['PYTHONPATH']"
  path1path2
  </code></pre>
  
  <p>What's wrong here?</p>
