FWIW, the background of this was that one of these examples overlapped
with a feature currently in development and it just caused a waste of
everyone's time by firstly "fixing" (removing) the extra comma and
then getting multiple code reviews saying the change was unrelated to
that feature and so having to remove that fix again. So I felt
removing all such commas at HEAD not only makes all the enums
consistent, but it may prevent similar time-wasting for others in the
future.
