build(deps-dev): bump black from 20.8b1 to 21.4b1

[dependabot-preview]

Bumps black from 20.8b1 to 21.4b1.

Release notes

Sourced from black's releases.

21.4b1

Black

• Fix crash on docstrings ending with "\ ". (#2142)

• Fix crash when atypical whitespace is cleaned out of dostrings (#2120)

• Reflect the --skip-magic-trailing-comma and --experimental-string-processing flags in the name of the cache file. Without this fix, changes in these flags would not take effect if the cache had already been populated. (#2131)

• Don't remove necessary parentheses from assignment expression containing assert / return statements. (#2143)

Packaging

• Bump pathspec to >= 0.8.1 to solve invalid .gitignore exclusion handling

21.4b0

Black

• Fixed a rare but annoying formatting instability created by the combination of optional trailing commas inserted by Black and optional parentheses looking at pre-existing "magic" trailing commas. This fixes issue #1629 and all of its many many duplicates. (#2126)

• Black now processes one-line docstrings by stripping leading and trailing spaces, and adding a padding space when needed to break up """". (#1740)

• Black now cleans up leading non-breaking spaces in comments (#2092)

• Black now respects --skip-string-normalization when normalizing multiline docstring quotes (#1637)

• Black no longer removes all empty lines between non-function code and decorators when formatting typing stubs. Now Black enforces a single empty line. (#1646)

• Black no longer adds an incorrect space after a parenthesized assignment expression in if/while statements (#1655)

• Added --skip-magic-trailing-comma / -C to avoid using trailing commas as a reason to split lines (#1824)

• fixed a crash when PWD=/ on POSIX (#1631)

• fixed "I/O operation on closed file" when using --diff (#1664)

• Prevent coloured diff output being interleaved with multiple files (#1673)

• Added support for PEP 614 relaxed decorator syntax on python 3.9 (#1711)

... (truncated)
