PEP-8: clarify if multiline argument list with a closing `)` on a separate line is acceptable

[guido (Guido van Rossum)]

I would prefer PEP 8 to explicitly discourage putting ): on a line by itself, since I find it ugly, Black notwithstanding. This is different from putting the last bracket of a tuple, list or call on a line by itself, since there’s nothing following that’s indented relative to the start of the construct.
