If this line was forgotten or somehow else put there, you can see in the Git repository. There you can check each single commit. I already did when the topic "wrong line" was brought up and the result is: The line was always there and has just been forgotten to be removed. There even was one last commit, which especially updated the README file; however: This line was forgotten.

As for your rollback problem it is hard to say what caused this without having more information and an exact error message. However, please put this to a different thread, should you still be in need of a solution for that!
