Before this change, all files that exist since 20th century had copyright headers, while most files that appeared later didn't. This change fixes the inconsistency by adding missing copyright headers. It doesn't mean that copyright headers became maintained. In my view, git history provides much better information on this subject and is much more accurate than copyright headers.
