[PATCH] git-gui: do not use obsolete `git merge $msg HEAD $branch'

From: Johannes Sixt <j6t@kdbg.org>
Date: Dec 16, 2015, 21:44 UTC
Message-ID: <5671DB28.8020901@kdbg.org>

Use the modern `git merge' invocation pattern.

Since both `git merge' and `git fmt-merge-msg' obey the merge.log configuration, instruct the former not to generate the log summary to avoid that it appears twice in the commit message.
