docstring formatting style "nil" is not like regular string

[holger (lp)]

With the change in revision 1994 of file python-mode.el the strings are now formatted (M-q, fill-paragraph) without an additional newline. This is good. But if py-docstring-style is set to nil, then docstrings still get that additional newline. So either the documentation is wrong, or the code is wrong. The documentation of py-docstring-style reads:

"A value of NIL won't care about quotes position and will treat docstrings a normal string"

Example:

class MyClass(object):
    """fff"""

    def my_method(self):
        """Some long line with more than 70 characters in the docstring. Some more text."""

       abcdefghijkl = """Some long line with more than 70 characters in the docstring. Some more text."""

This is formatted as (py-docstring-fill-column set to 70):

class MyClass(object):
    """fff"""

    def my_method(self):
        """Some long line with more than 70 characters in the

        docstring. Some more text."""

        abcdefghijkl = """Some long line with more than 70 characters
        in the docstring. Some more text."""

BTW, without a newline between the docstring and variable abcdefghijkl the formatting doesn't work at all if you start to format the string of the variable.
