title: using 'from __future__' with ipython and PYTHONSTARTUP
body: <p>I would like to have</p>
  
  <pre><code>from __future__ import (absolute_import, division, print_function, unicode_literals)
  </code></pre>
  
  <p>loaded in each interactive session, using a <code>PYTHONSTARTUP</code> file. This works with basic python (2.7.5, installed with Anaconda), but does not work with ipython (1.0.0, Anaconda). Other <code>import</code> statements work with ipython, but <code>__future__</code> ones are just ignored (although they work if I enter them on the command line). Is this an ipython bug, or is there something I'm missing?</p>
