From 126facf8219177bc265be725a8579c86ebdf99a5 Mon Sep 17 00:00:00 2001 From: Eric Sunshine Date: Sun, 22 Jul 2018 05:57:05 -0400 Subject: format-patch: add --interdiff option to embed diff in cover letter When submitting a revised version of a patch series, it can be helpful (to reviewers) to include a summary of changes since the previous attempt in the form of an interdiff, however, doing so involves manually copy/pasting the diff into the cover letter. Add an --interdiff option to automate this process. The argument to --interdiff specifies the tip of the previous attempt against which to generate the interdiff. For example: git format-patch --cover-letter --interdiff=v1 -3 v2 The previous attempt and the patch series being formatted must share a common base.
