This is not a new feature or a bug. This is a result of something you guys committed unknowingly. Remember, Git is tracking all changes to the binary data of your repo. Several types of changes could have caused this. Has anyone copied the whole text of this document from one editor to another, replacing the original with the copy (perhaps across different operating systems)? Has the character set your project is using changed lately? Other things can cause this type of change detection too, but what is important to understand is that this is not an error on Git's part.
