There are two reasons why I normally sign-off. One is reviewed code and the other is copyright assignment. Although Pry doesn't have a DCO it's become good practice to almost always certify your code as written by you or uploaded by you saying that you take full responsibility for any copyright issues -- normally you would do it on big patches but in my case I turn it on by default for any patch that I send or commit. http://kerneltrap.org/files/Jeremy/DCO.txt
