This will update all the `*.stderr` files in `clippy_tests/examples`. You need to check
the stderr files whether they look as you expected them and commit them together with your
changes.
When you want to test a new lint, just create a new file in `clippy_tests/examples` and
rerun `cargo test examples`.
You can check just one example by running `cargo run --example example_name` inside the
