(Normally it only does so in recursive invocations, but not for the final result.) This serves as a building block for the "remerge diff" feature coming up in a subsequent patch. The external option lets us easily use it from tests, where we'd otherwise need a new test-* helper to access the feature. Furthermore, it might occasionally be useful for scripts that want to look at the result of invoking git-merge without tampering with the worktree. They could already get the _conflicts_ with --index-only, but not (conveniently) the conflict-hunk formatted files that would normally be written to the worktree.
