Rollup merge of #109793 - lukas-code:negative-impl-comment, r=scottmcm
add comment to `impl !Error for &str` I saw this impl in the [standard library docs](https://doc.rust-lang.org/nightly/core/error/trait.Error.html#impl-Error-for-%26str) and wondered why it's needed. This commit adds a comment to explain its existence.
