2527 * Improve code examples across multiple lints [#5664](https://github.com/rust-lang/rust-clippy/pull/5664)
2531 * Introduce a `--rustc` flag to `clippy-driver`, which turns `clippy-driver`
2532 into `rustc` and passes all the given arguments to `rustc`. This is especially
2533 useful for tools that need the `rustc` version Clippy was compiled with,
2534 instead of the Clippy version. E.g. `clippy-driver --rustc --version` will
2535 print the output of `rustc --version`.
