From 3d09c22869a7bd47f1683031937af0ed93b2fa3b Mon Sep 17 00:00:00 2001 From: Denton Liu Date: Mon, 14 Sep 2020 11:36:52 -0700 Subject: builtin/diff-tree: learn --merge-base The previous commit introduced ---merge-base a way to take the diff between the working tree or index and the merge base between an arbitrary commit and HEAD. It makes sense to extend this option to support the case where two commits are given too and behave in a manner identical to `git diff A...B`. Introduce the --merge-base flag as an alternative to triple-dot notation. Thus, we would be able to write the above as `git diff --merge-base A B`.
