Sphinx crashes on code block inside itemize

[nthiery]

Thank you again for the sphinx-contrib-jupyter example; it enabled me to reduce the crash I was getting on my own rest files to a minimal non working example:

Steps to reproduce:

• Create a file foo.rst, with the following content, e.g. inside sphinxcontrib-jupyter.minimal:

• Create the permutation

  .. code-block:: python3

  1+1

• Run make jupyter

  make jupyter                                                                                                            master  ✱

Thanks @nthiery. Nice bug report. Supporting directives within lists/itemize is something we will need to support.

The tests case for lists.rst now includes embedded code-blocks. However the indentation is limited in the markdown representation, and this really only works at the moment for non-enumerated list types. The enumerated list numbering get's reset.
