reStructuredText `code` and `code-block` directives regression

[ergoithz]

Confirmed regression of issue #106 reStructuredText code and code-block directives

[nickwilliams-eventbrite]

This seems to be partially working. If I put .. code-block:: python in my RST file, it renders correctly on GitHub. However, if I add the :linenos:, :emphasize-lines:, :caption:, and/or :name: directives to those code blocks, the blocks just disappear. I understand that perhaps GitHub can't do the extra rendering requested by those directives, but, in that case, they should just be ignored no-ops. It definitely should not make the entire code block completely disappear from the rendered document. :-/

Is this a limitation of docutils?
