Subject: [PATCH v2 09/15] merge-recursive: track branch where rename occurred in rename struct
Date: Fri, 29 Mar 2019 17:33:30 -0700	[thread overview]
Message-ID: <20190330003336.21940-10-newren@gmail.com> (raw)
In-Reply-To: <20190330003336.21940-1-newren@gmail.com>

We previously tracked the branch associated with a rename in a separate
field in rename_conflict_info, but since it is directly associated with
the rename it makes more sense to move it into the rename struct.
