So there is no point in using the dir-diff mode when you have say two extracts of pristine tarballs? I guess that's true. The difftool will launch an external "directory diff tool" on two directories populated with the two "things" (be it "the contents from a tree-ish", "the working tree files", "the contents in the index") in the end, but you already have two directories to be compared when you run "diff --no-index", so there is no point in going through the "difftool" middleman. You can just feed the two directories you have directly to that external directory diff tool. > base-commit: 20de316e33446f37200e51aa333ba7d824dfd478 > Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-186%2Fdscho%2Fdifftool-no-index-extra-v1 > Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-186/dscho/difftool-no-index-extra-v1 > Pull-Request: https://github.com/gitgitgadget/git/pull/186
