The index is a file in .git/ that serves many purposes. NEXT is an image of the whole project. NEXT can be computed from the index and HEAD.

During a conflicted merge, stage 0 of the index holds the resolved files. WTREE holds all merge files: the resolved and the unresolved (which have <<<< ==== >>>> blocks in them). I propose that during a conflicted merge, that NEXT be computed as HEAD plus the resolved files, that is, the files in stage 0 of the index.

"git diff HEAD NEXT" would print the resolved changes. "git diff NEXT WTREE" would print the unresolved changes "git diff HEAD WTREE" would print all changes.

I believe that is the same behaviour as "git diff", "git diff --cached" and "git diff HEAD" during a conflicted merge.

I do not know how "n-way" merge works. I saw somewhere that indicated that it was a series of N-1 two-way merges.
