I've seen a trailing white line at the end of Python docstrings (like in Numpy docstrings and in Google style docstrings, and I recall having read somewhere that this was suggested.
That said, they seem to be ignored in docstring converters, such as in Napolean and in the example routine in the PEP-257 docs.
What is the purpose for adding a trailing white line in Python docstrings? Is it purely for legibility?
