As far as I can see, Sphinx has a global setting for trim_doctest_flags but lacks the possibility of locally disabling the trimming.
A quick workaround would be to have the following sphinx extension added:
class ProxyLexer(object):
 def __init__(self, underlying):
 self.__underlying = underlying
 def __getattr__(self, attr):
 return getattr(self.__underlying, attr)
def setup(app):
 from sphinx.highlighting import lexers
 if lexers is not None:
 lexers['pycon-literal'] = ProxyLexer(lexers['pycon'])
 lexers['pycon3-literal'] = ProxyLexer(lexers['pycon3'])
That would allow blocks marked as
.. code-block:: pycon-literal
or preceded by 
.. highlight:: pycon-literal
to escape the trimming of doctest flags.
If that's of any interest I can submit a patch.
