universal_newlines attribute of Popen() broken

[GoogleCodeExporter]

Using subprocess.py on Windows XP, Python 3.1.

Exception happened during processing of request from ('127.0.0.1', 1598)
Traceback (most recent call last):

    read = self._translate_newlines(read)
TypeError: _translate_newlines() takes exactly 3 positional arguments (2 given)

Checked out the code, at lines 960 and 1002 the encoding parameter is missing, 
while the definition at line 814 doesn't set a default value for the encoding.  
For now I added the 'self.stdout.encoding' values to lines 960 and 1002 since 
you can't set the function's default as that.
