[PATCH 11/41] tree-walk: avoid hard-coded 20 constant

From: brian m. carlson <sandals@crustytoothpaste.net>
Date: Apr 23, 2018, 23:39 UTC
Message-ID: <20180423233951.276447-12-sandals@crustytoothpaste.net>
In-Reply-To: <20180423233951.276447-1-sandals@crustytoothpaste.net>

Use the_hash_algo to look up the length of our current hash instead of hard-coding the value 20.
