[style] rustfmt `match`es with comments in or-patterns Using https://github.com/rust-lang/rustfmt/pull/6893, I reformatted the whole codebase. The result is that `match`es that *should have* been formatted under normal circumstances but are getting skipped now got their expected format. These match expressions were being entirely skipped because they contain or-patterns with comments in between patterns, causing rustfmt to bail out entirely. The or-patterns with comments themselves remain untouched, but now the match arm bodies and other patterns without comments do get formatted under that PR. Because the fix in rustfmt isn't landed yet, I reworked some of the or-patterns with comments so that formatting doesn't regress. Tried doing this only in larger blocks that are more likely to regress in the meantime. (Introduced and) removed a bunch of stray backticks \` likely left after an editor autoclosed the intended closing \`, resulting in <code>\`name\`\`</code> in comments.
