Ruff now supports `ruff: ignore` comments at the ends of lines, like `noqa` comments, or on the line preceding a diagnostic. For example, these both suppress an [`unused-import`](https://docs.astral.sh/ruff/rules/unused-import/) (`F401`) diagnostic:

Fixes are now shown in `check` and `format --check` output: ````console ❯ ruff format --check . unformatted: File would be reformatted --> try.md:1:1 | 1 | ```python

import math 2 + import math 3 | ``` | 1 file would be reformatted ```` This example also shows off the Markdown formatting.
