I'm afraid your description is a bit too vague for me to be able to give you much advice. How do the original (say diff-mode) buffer and your mydiff buffer differ (or how are they related)? Is `mydiff` generated from `diff`? What do you mean by "gutter"? > so part of the problem is finding the corresponding line in orig for > each line in mydiff, If `mydiff` is generated from `diff`, presumably you can get this info by remembering this original mapping (e.g. adding text-properties in `mydiff` that point to the origin, so that as you modify `mydiff`, the origin info is preserved).
