Line 842 in d4bbf71

text = ''.join(self._current_paragraph)

might need to be:

            text = '' if self._current_paragraph is None else ''.join(self._current_paragraph)

but then the indent for "sub-detail 2.2" doesn't align correctly.

This is not valid rst: indeed, docutils emits <string>:10: (ERROR/3) Unexpected indentation. to stderr.
In master I'm changing that so that docutils propagates the exception out.
