With the exception of `tests/run-make/translation/test.rs`, which has a syntax error. The expected output in `rustdoc-error-lines/rmake.rs`'s required slight tweaking. The two `reproducible-build.rs` files need `// ignore-tidy-linelength` because rustfmt produces lines longer than 100 chars, which tidy doesn't like, yuk.
