Subject: [PATCH v4 05/12] t0027: make hash size independent
Date: Mon,  3 Sep 2018 23:25:08 +0000	[thread overview]
Message-ID: <20180903232515.336397-6-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20180903232515.336397-1-sandals@crustytoothpaste.net>

We transform various object IDs into all-zero object IDs for comparison.
Adjust the length as well so that this works for all hash algorithms.

While it would be slightly more efficient to use a sed y/// expression
instead of both the tr and sed, retain the tr in both cases for
parallelism and compactness.
