From df5d43be1f721b0ede37097b815463ceb43b0449 Mon Sep 17 00:00:00 2001 From: Ralf Thielow Date: Wed, 1 Dec 2010 20:15:59 +0100 Subject: [PATCH] commit.c: Remove backward goto in read_craft_line() Bad graft data is noticed in several places in read_graft_line(), and in each case we go back to the first site of detection. It in general is a better style to have an exception handling out of line from the main codepath and make error codepath jump forward.
