[PATCH v2 09/53] builtin/rev-parse: convert to struct object_id

From
brian m. carlson <sandals@crustytoothpaste.net>
Date
May 1, 2017, 02:29 UTC
Message-ID
<20170501022946.258735-10-sandals@crustytoothpaste.net>
In-Reply-To
<20170501022946.258735-1-sandals@crustytoothpaste.net>

Some of the functions converted are callers of lookup_commit_reference. However, the changes involved in converting the entire thing are not too large, so we might as well convert it all.
