Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @Mark-Simulacrum (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

You need to run x.py fmt:

 If you're running `tidy`, try again with `--bless`. Or, if you just want to format code, run `./x.py fmt` instead.
     let config = Config::parse(&args);
 
     // check_version warnings are not printed during setup
-    let changelog_suggestion = if matches!(config.cmd, Subcommand::Setup {..}) {
-        None
-    } else {
-        check_version(&config)
-    };
+    let changelog_suggestion =
+        if matches!(config.cmd, Subcommand::Setup {..}) { None } else { check_version(&config) };

r=me after that, thanks so much for working on this!

also, if you could squash the commits, that would be great: https://rustc-dev-guide.rust-lang.org/git.html#advanced-rebasing. I won't block on that though.
