### What it does In the Linux kernel we had some documentation examples added with triple backquotes at the end without indentation. Such a lint would find a few hits, e.g. there is currently one in `core`. Possibly related, at least implementation-wise: https://github.com/rust-lang/rust-clippy/issues/15024 and https://github.com/rust-lang/rust-clippy/issues/15025. ### Advantage - More consistency in docs. - Less time spent by reviewers. ### Drawbacks _No response_ ### Example ```rust /// ``` /// fn f() {} ///``` ``` Should be written as: ```rust /// ``` /// fn f() {} /// ``` ```
