This also removes names if they don't have an email attached, while the original code puts the name in with empty email. Ahh, sorry, there's an if _email at the end, I don't seem to be able to read a diff (at least while feeding a baby).

Looking at https://packaging.python.org/en/latest/specifications/pyproject-toml/#authors-maintainers, I think the new behavior is likely correct, though I think it might not handle missing name correctly still. No, formataddr does this correctly: email.utils.formataddr(("", "[email protected]")) returns [email protected].

@henryiii anything I can help with to get it merged?

I'm waiting on pre-commit to be reactivated (#90) then will merge this.
