Title: Fixes `header': wrong number of arguments (3 for 2)

I don't know if it's because of my version of RedCarpet (3.1.1) but I'm getting these errors. The 3rd argument seems to be the lower-cased version of the first argument (maybe an ID ?). In any case, that change should be backward-compatible
