Y020: False positive with string default

[srittau]

See python/typeshed#9546 for reference. Y020 is triggered on the following definition:

from typing_extensions import Literal

def foo(bar: str = "x") -> None: ...

An empty default string does not trigger the warning.

Already fixed in #318, I believe — just needs a release :)

Should we do a release soon? You made a bunch of improvements too; unless you have more in the works I think it's time.

I was just about to post and ask if anybody had anything else they wanted to be included in the next release; otherwise I think it's time as well :)
