- when a trailing comma is specified in any bracket pair, that signals to Black that this bracket pair needs to be always exploded, e.g. presented as "one item per line"; - this causes some changes to previously formatted code that erroneously left trailing commas embedded into single-line expressions; - internally, Black needs to be able to identify trailing commas that it put itself compared to pre-existing trailing commas. We do this by using/abusing lib2to3's `was_checked` attribute. It's True for internally generated trailing commas and False for pre-existing ones (in fact, for all pre-existing leaves and nodes). Fixes #1288
