pylint #103656 False positive W0231 for missing object.__init__ [validation pending]

In some cases, pylint raise W0231 (__init__ method from base class %r is not called) when base class for __init__ is object. FE:

class NoInit(object):
    """No __init__ defined"""

class Init(NoInit):
    """Don't complain for not calling the super __init__"""

    def __init__(self, arg):
        self.arg = arg

Confirmed on Mac OS X, with last pylint/logilab-astng versions. Proposed patch attached. From
