Is it possible to save conflict contents to a new .rej file?

[hao-lee]

I think it would be better to provide a option that saves conflict contents to a new .rej file. Then I can resolve them manually as there won't be too many conflicts after wiggling.

I might make sense to add such an option, and it should be fairly easy to do.
However I have no interest in working on it at the moment. If you would like to try writing some code, I would be happy to review any patch you produce, or to provide suggestions if you cannot see how to get started.
