Subject: [RFC PATCH v2 16/22] blame: rework methods that determine 'final' commit
Date: Sat, 13 May 2017 22:15:07 -0500 [thread overview]
Message-ID: <20170514031513.9042-17-whydoubt@gmail.com> (raw)
In-Reply-To: <20170514031513.9042-1-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.
