Change .. code:: to .. code-block::

Sphinx uses .. code-block:: directives to enable highlighting:
http://sphinx-doc.org/markup/code.html#directive-code-block

Use

  for i in *.rst; do
        sed -i 's/code::/code-block::/g' $i
    done

to update these strings to enable proper highlighting.

Note: A have disabled the windows "bash" one, because the highlighting
is broken anyway...
