It seems to me that what is needed is the ability to pass the complete unmerged state on. That is, we need something like five commits, made in a way similar to the way a stash is made: * all resolved (stage 0) index entries (1 tree) * all index stage 1, 2, and 3 entries (3 trees) * and the current work-tree (1 tree) This isn't quite complete as we also need the merge information; perhaps that goes into a sixth commit, or can be wedged into the commit message text of one (or more?) of the five trees. The "resume unresolved merge" command then must unpack all of this into the appropriate places. Chris
