Note that this is solvable.  Put a comma at the end of your initializer
list, always.  This works for enums, array initializers, and AFAIK just
arbitrary cases of comma separated things between curly braces.  I
personally think that it's absolutely ridiculous that this "hack" exists
and that there is no proper clang-format style option, but then again..  I
haven't proposed or contributed a fix, so I'm not exactly helping.
