Update tests for Python 3.13, add nocover in pshell

Inner functions such as:

    def outer():
        def inner():
            pass

Now have an attribute called `__name__`, which will be set to `inner`.

Also it seems that there is a `__doc__` attribute that is now standard,
and thus we add a pragma nocover to pshell.
