[New-bugs-announce] [issue41167] Add new formats to PyArg_ParseTuple for "str or None"

[Inada Naoki]

New submission from Inada Naoki <songofacandy at gmail.com>:

PyArg_ParseTuple has 'U' format for getting Unicode as PyObject*.
But when user want accept "str or None", they are forced to use 'O&' and write a custom converter. It is not convenient.

I am proposing to add 'U?' for "str or None" variants of 'U'. Does it make sense?
