Reformatting print()s that span multiple lines does not remove extraneous "s

[cricalix]

Operating system: Linux
Python version: 3.6.3rc1
Black version: 18.4a1
Does also happen on master: Yes (18.4a3 cloned today)

Original code:

            self.logger.debug(
                f'Skipped {skipped_count} virtual '
                f'interfaces for {device.name}'
            )

black'd code:

            self.logger.debug(
                f"Skipped {skipped_count} virtual " f"interfaces for {device.name}"
            )

Could black detect that it's done this (with or without f-string markers), and remove the ' " " ' that results, or is that considered too invasive a change to the code?
