It's mentioned as the preferred way to reference commits in SubmittingPatches (search for %ad). But I don't see why it is "not a footer". The "Fixes:" key conforms to the trailer syntax, and the value of a trailer is free-form. Running: git log --format='%(trailers:key=Fixes)' shows that Git is happy with it. And indeed, a few other people have used it before you. None of them with a date. ;) -Peff
