parsed-literal output

Hi,

I have realized that the html output of parsed-literal depends on whether links are included or not. For instance:

.. parsed-literal::

   public int64  size()

will generate a single line with highlighted code

but

.. parsed-literal::

   public :ref:`fusion.flatexpr`  eval()

will yield a single line but with not highlight. Note that the link is valid and it will work nicely.

My point is: there should be a consistent behaviour. Of course would be nice to have always highlight (or an option to have it).
