[PATCH v2 16/35] builtin/am: make hash size independent

From
brian m. carlson <sandals@crustytoothpaste.net>
Date
Feb 19, 2019, 00:05 UTC
Message-ID
<20190219000526.476553-17-sandals@crustytoothpaste.net>
In-Reply-To
<20190219000526.476553-1-sandals@crustytoothpaste.net>

Instead of using GIT_SHA1_HEXSZ, switch to using the_hash_algo and parse_oid_hex to parse the lines involved in rebasing notes.
