title: Does \r stand for something in sphinx?
body: <p>I'm writing my docstring following the numpy docstring guidelines. Then I use sphinx's autodoc to generate my documentation. Within some docstrings I'm using LaTeX formulas (sphinx.ext.mathjax). It seems that <code>\r</code> means something special like a new line. If I have the following command:</p>
  
  <pre><code>"""
  This :math:`\langle a, b\rangle` denotes the dot product of a and b
  """
  </code></pre>
  
  <p>it doesn't properly render. It puts like angle to a new line and gives me an error: <em>Inline interpreted text or phrase reference start-string without end-string</em>
  If I replace the \rangle with \langle everything works fine. How can I fix this?</p>
