From 1055997e2fc707a15baf232df2ac481055c14321 Mon Sep 17 00:00:00 2001 From: Denton Liu Date: Wed, 17 Apr 2019 11:23:28 +0100 Subject: merge: add scissors line on merge conflict This fixes a bug where the scissors line is placed after the Conflicts: section, in the case where a merge conflict occurs and commit.cleanup = scissors. Next, if commit.cleanup = scissors is specified, don't produce a scissors line in commit if one already exists in the MERGE_MSG file.
