Thanks. Could you recommit with -s option to pass DCO check?

[sandstrom]

@repeatedly I'm against DCOs in general, and especially against them for small changes of code and documentation changes (they serve no legal purpose for docs, for example). I understand that having these aren't your decision, so I'm not going to argue more about it here, but I think they do hamper contributions and add unnecessary friction. 😄

That said, I've updated the commit! Merge away ⛵️
