<!-- Thank you for taking the time to report an issue! We're glad to have you involved with Ruff. If you're filing a bug report, please consider including the following information: - A minimal code snippet that reproduces the bug. - The command you invoked (e.g., `ruff /path/to/file.py --fix`), ideally including the `--isolated` flag. - The current Ruff settings (any relevant sections from your `pyproject.toml`). - The current Ruff version (`ruff --version`). --> Similar to the what darker does for black, it would be very nice for introducing ruff to a code base to only apply it to changed lines.
