- 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 |

Commit hash: 9c17e3a1987004b8bcfbe423953aad84493a7984 Reasons for forking: - consistent handling of f-strings for users of Python < 3.6.2 - backport of BPO-33064 that fixes parsing files with trailing commas after *args and **kwargs - backport of GH-6143 that restores the ability to reformat legacy usage of `async` - support all types of string literals - better ability to debug (better reprs) - INDENT and DEDENT don't hold whitespace and comment prefixes - ability to Cythonize Change Log: - Changes default logger used by Driver
