From d1f87a2d9c4877ada003c231b92de7560eab62ed Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 13 Aug 2018 04:33:28 -0700 Subject: [PATCH] range-diff: left-pad patch numbers As pointed out by Elijah Newren, tbdiff has this neat little alignment trick where it outputs the commit pairs with patch numbers that are padded to the maximal patch number's width: 1: cafedead = 1: acefade first patch [...] 314: beefeada < 314: facecab up to PI! Let's do the same in range-diff, too.
