bug#21583: 25.0.50; Python mode uses wrong indentation in docstrings

[Torsten Bronger]

When using python-mode and auto-fill-mode and writing docstrings for
Python methods, a function/method decorator confuses python-mode so that
it uses a too small indentation for a new line.  Have a look at this
example:

class A:

    @property
    def a(self):
        """This is property a.  blah blah blah blah blah blah blah blah blah
    blah blah blah blah blah blah blah blah blah blah   

        """

If the "@property" line is removed, the second line in the docstring is
properly indented.
