From faa1df86dc033ce1e6136ed89ad55df1bd479099 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 13 Aug 2018 04:33:18 -0700 Subject: [PATCH] range-diff: use color for the commit pairs Arguably the most important part of `git range-diff`'s output is the list of commits in the two branches, together with their relationships. For that reason, tbdiff introduced color-coding that is pretty intuitive, especially for unchanged patches (all dim yellow, like the first line in `git show`'s output) vs modified patches (old commit is red, new commit is green). Let's imitate that color scheme.
