Oh, I hate to do this but I ended up merging big usage string cleanups from Fredrik, git-am enhancements that made a lot of sense for non mbox users from HPA, and rebase changes (done independently by me and Lukas) among other things, so git is still in perpetual state of 1.0rc. 1.0 will probably be next Wednesday, but who knows.
