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"?

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).
