Hmm, you are right. That's a bit awkward, git doesn't actually track authors, it just tracks committers. So there's actually a bunch of authors, and krh is just committing for them. Woops, sorry about that :) Would like to see a graph that shows authorship though, very interested in how large and active the wayland dev team actually is.

It paints a very different picture about the distribution of authorship.
