In rust-lang#7571, we added checks for crate names that added or removed suffixes from popular crates. This has turned out to be a useful check! (Spoiler alert for the blog post I'm publishing next week.) @Turbo87 pointed out that this can also apply to prefixes, especially `cargo-`. This generalises the suffix check to also check prefixes, and adjusts the typomania configuration to add `cargo` to the list of interesting affixes. For now, the same set of affixes will be used for both, but depending on what we see, a future tweak would be to separate the prefix and suffix lists. Let's see how that pans out. In terms of implementation, I briefly toyed with making this generic over the prefix/suffix combination to remove the copy/paste code, then was reminded by rust-analyzer that `std::str::pattern::Pattern` isn't stable. I'd rather duplicate 20 lines than deal with that, so here we are.
