Can we use is_part_of_annotation to simplify some of the logic in the next check too? Lines 1092-1099?

[RedGuy12]

I tried, but it ended up adding a lot of unrelated changes to this PR since is_part_of_annotation currently checks for both return and parameter annotations. I can do that refactor in a future PR.

[hauntsaninja]

Thank you for all you recent PRs!

No idea why diff-shades is detecting changes in stable style now, I only merged upstream in and didn't change any logic. Additionally, it's only finding changes when linting Black itself, past diff-shades runs showed changes in other projects on preview style (compare stable run today and preview run Wednesday)

[JelleZijlstra]

I suspect it's because Black itself is now formatted with unstable = true and diff-shades maybe doesn't handle that correctly.

ichard26/diff-shades#15 as a quick patch

[JelleZijlstra]

Looks good. I'll fix the one minor issue, then hopefully diff-shades will succeed if I retry.

[JelleZijlstra]

Maybe ichard26/diff-shades#16 helps, trying again.

[JelleZijlstra]

diff-shades succeeded (not sure it's because of my changes, as it was apparently already using 4 processes). Quite a few changes, but they all look expected.
