From: Johannes Schindelin via GitGitGadget Date: Sat, 21 Jul 2018 22:05:11 GMT Subject: [PATCH v4 19/21] range-diff: left-pad patch numbers Message-ID: <07ec215e83d73ab5d0cb6221c243b24d58694b6d.1532210683.git.gitgitgadget@gmail.com> In-Reply-To: From: Johannes Schindelin 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.
