Interesting, this passed the Windows CI.  My best guess is that this is a line ending issue with the `diff` command. We might need to pass `-Z` or avoid the diff command altogether. This could depend on if git is configured to checkout CRLF line-endings or not. I don't have a Windows machine set up, so no good way to quickly troubleshoot this.
