Single quotes in triple-quoted docstring raise AssertionError

[jacobtylerwalls]

👋 !

Some chatter in the Django forum today about whether to lint docstrings, so I gave this project a test drive on Django, and noticed an error on a source like this:

def a(self):
    "'a.m.' or 'p.m.'"
    if self.data.hour > 11:
        return _("p.m.")
    return _("a.m.")

pydocstringformatter a.py
