[PATCH v2 08/35] submodule: avoid hard-coded constants

From
brian m. carlson <sandals@crustytoothpaste.net>
Date
Feb 19, 2019, 00:04 UTC
Message-ID
<20190219000526.476553-9-sandals@crustytoothpaste.net>
In-Reply-To
<20190219000526.476553-1-sandals@crustytoothpaste.net>

Instead of using hard-coded 40-based constants, express these values in terms of the_hash_algo and GIT_MAX_HEXSZ.
