#116adapt to darcs 2.9's new hash format
http://hub.darcs.net/simon/darcsden/patch/20141009053949-81bb2 fixed #111 for now. If darcs's hashes are becoming simpler it would be nice to use them, so we may need to do more here at some point. An issue is whether old patch urls can be kept working, if that matters (cf #114).
