From 4c0ea82da3cd35eff50377cab78208c8ef57933b Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 4 Nov 2011 17:00:03 -0700 Subject: [PATCH] fmt-merge-msg: avoid early returns In various places in the codepath, the program tries to return early assuming there is no more work needed. That is generally untrue when over time new features are added.
