Subject: [PATCH 20/29] blame: rework methods that determine 'final' commit
Date: Wed, 24 May 2017 00:15:28 -0500 [thread overview]
Message-ID: <20170524051537.29978-21-whydoubt@gmail.com> (raw)
In-Reply-To: <20170524051537.29978-1-whydoubt@gmail.com>
Either prepare_initial or prepare_final is used to determine which
commit is marked as 'final'. Call the underlying methods directly to
make this more clear.
