changelog: [`doc_suspicious_footnotes`]: lint for text that looks like a footnote reference but has no definition This is an alternative to https://github.com/rust-lang/rust/pull/137803, meant to address the concerns about false positives. This lint only fires when the apparent footnote reference has a name that's made from pure ASCII digits. This choice is justified by running lintcheck on the top 200 crates, plus the clippy default set: 1. [I ran lintcheck](https://gist.github.com/notriddle/59072476c9c1fd569fee421270dad665) with a modded version of this lint that didn't check for digits only. It produced a false positive warning on a line in mdbook that had a regex, and no true positives at all. 2. [I also ran lintcheck](https://gist.github.com/notriddle/74eb8c9e1939b9f5c5549bf1d4fa238a) with a custom lint that fired on any valid footnote reference with a non-ascii-digit name. `cargo` uses one in its job_queue module, and that's all it found. cc @GuillaumeGomez |
