Omar Sandoval 36068a0ea8 Fix trailing commas for Black v20.8b1
Black was recently changed to treat a trailing comma as an indicator to
put each item/argument on its own line. We have a bunch of places where
something previously had to be split into multiple lines, then was
edited to fit on one line, but Black kept the trailing comma. Now this
update wants to unnecessarily split it back up. For now, let's get rid
of these commas. Hopefully in the future Black has a way to opt out of
this.
