Summary

While the --cap-lints flag is correctly taken into account when using cargo clippy, it is ignored when using cargo clippy --fix.

running: cargo clippy --fix -- --cap-lints=allow

I expected to see this happen:

Nothing, same behaviour as for RUSTFLAGS="--cap-lints=allow" cargo clippy --fix

Instead, this happened:
