From f5e375c9a99d731c05eef701f119da85d62fc158 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 22 Aug 2005 23:16:46 -0700 Subject: [PATCH] Clean-up output from "git show-branch" and document it. When showing only one branch a lot of default output becomes redundant, so clean it up a bit, and document what is shown. Retire the earlier implementation "git-show-branches-script".
