From 3b41fcbd96610dc0fddded2aebc4e3b5c702b4fb Mon Sep 17 00:00:00 2001 From: Stefan Lay Date: Fri, 15 Feb 2013 12:34:44 +0100 Subject: [PATCH] Accept Change-Id even if footer contains not well-formed entries Instead of only looking for a Change-Id in the last section if it consists only of well-formed "key: value" lines replace the last occurrence of a valid Change-Id line in the last section. Some tools require footer lines e.g. without a colon. Gerrit doesn't accept Change-Id lines in the footer if the Change-Id line doesn't start at the beginning of the line.
