py-black: updated to 22.8.0

22.8.0

Highlights

- Python 3.11 is now supported, except for _blackd_ as aiohttp does not support 3.11 as
  of publishing
- This is the last release that supports running _Black_ on Python 3.6 (formatting 3.6
  code will continue to be supported until further notice)
- Reword the stability policy to say that we may, in rare cases, make changes that
  affect code that was not previously formatted by _Black_

Stable style

- Fix an infinite loop when using `# fmt: on/off` in the middle of an expression or code
  block
- Fix incorrect handling of `# fmt: skip` on colon (`:`) lines
- Comments are no longer deleted when a line had spaces removed around power operators

Preview style

- Single-character closing docstring quotes are no longer moved to their own line as
  this is invalid. This was a bug introduced in version 22.6.0.
- `--skip-string-normalization` / `-S` now prevents docstring prefixes from being
  normalized as expected
- When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from
  subscript expressions with more than 1 element
- Implicitly concatenated strings inside a list, set, or tuple are now wrapped inside
  parentheses
- Fix a string merging/split issue when a comment is present in the middle of implicitly
  concatenated strings on its own line

_Blackd_

- `blackd` now supports enabling the preview style via the `X-Preview` header

Configuration

- Black now uses the presence of debug f-strings to detect target version
- Fix misdetection of project root and verbose logging of sources in cases involving
  `--stdin-filename`
- Immediate `.gitignore` files in source directories given on the command line are now
  also respected, previously only `.gitignore` files in the project root and
  automatically discovered directories were respected

Documentation

- Recommend using BlackConnect in IntelliJ IDEs

Integrations

- Vim plugin: prefix messages with `Black: ` so it's clear they come from Black
- Docker: changed to a /opt/venv installation + added to PATH to be available to
  non-root users

Output

- Change from deprecated `asyncio.get_event_loop()` to create our event loop which
  removes DeprecationWarning
- Remove logging from internal `blib2to3` library since it regularly emits error logs
  about failed caching that can and should be ignored

Parser

- Type comments are now included in the AST equivalence check consistently so accidental
  deletion raises an error. Though type comments can't be tracked when running on PyPy
  3.7 due to standard library limitations.

Performance

- Reduce Black's startup time when formatting a single file by 15-30%
