Originally, ancient versions of Rust allowed you to nest block comments. Then we decided this was too surprising and too hard to parse, so we took it out. Then we decided that this was too useful to exclude so we added it back in, but apparently this time we forgot to update the manual. Just another day in the life of Rust! :)
