I suggest that StGIT saves the original patch and then does interdiff between the old and the new patch. The original patch is applied first just as it's applied now, and then the difference is applied on top of that. Temporary files should be kept in case of failure. > Other advantages of the three-way merging is the detection of full > patches or hunks merged upstream (the former can also be achieved by > testing the reverse-application of the patches). I'm fully with you here. Having git history can only be a good thing. > I don't usually edit patches during development, I prefer to edit the > source files and review the diff.

What I normally need to edit is the comments.

I hate to be in a situation when I want to edit something but cannot, because I didn't run some command before. What I like about StGIT is that it allows me to do things my way.
