This changes how we handle merges: if a automated merge fails, we will leave the index as a clean entry pointing to the original branch, and leave the actual file _dirty_ the way the "merge" program left it. You can then just do "git-diff-files -p" to see what the merge conflicts did, fix them up, and commit the end result. NOTE NOTE NOTE! Do _not_ use "git commit" to commit such a merge. It won't set the parents right. I'll need to fix that. In the meantime, you'd need to merge using git-commit-tree $(git-write) -p HEAD -p MERGE_HEAD or something like that by hand.
