docstring of django.db.models.Q causes warning when building Sphinx docs for my project

[Luc Saffre]

When I write

from django.db.models import Q

in my code, then I get a Sphinx warning when building the docs for my project. This is partly due to the fact that Sphinx's autodoc inserts the docstring of Django's Q class into my API doc. But the more obvious problem is that this docstring contains invalid reStructuredText content. The docstring is:

    Encapsulates filters as objects that can then be combined logically (using
    & and |).

Correct syntax must be::

    Encapsulates filters as objects that can then be combined logically (using
    `&` and `|`).
