I don’t mind the formatting, I mind that the formatting is done depending on wether the list ends with a comma or not.

    [
       Item1,
       Item2
    ]

Is combined to one line, while

    [
       Item1,
       Item2,
    ]

Stays as multi line. Now I am once again in charge of formatting my code, by virtue of the comma. Does this stay multi line or is it short enough enough to combine? That should be for black to decide not me!
