[issue3442] wsgiref.validate.InputWrapper.readline does not accept optional "length" argument

[Pavel Strashkin]

New submission from Pavel Strashkin <xaka2004 at gmail.com>:

All file/stream-like objects in Python have "readline" method with
optional "length" argument, but wsgiref.validate.InputWrapper doest not
have. Some 3rd party modules/packages use this argument. As result there
is exception:
<type 'exceptions.TypeError'>: readline() takes exactly 1 argument (2 given)

I think wsgiref.validate.InputWrapper.readline must be implemented same
to wsgiref.validate.InputWrapper.read:

def readline(self, *args, **kwargs):
    v = self.input.readline(*args, **kwargs)
    assert_(type(v) is type(""))
    return v
