[PATCH v3 17/53] tag: convert parse_tag_buffer to struct object_id

From: brian m. carlson <hidden>
Date: 2017-05-06 22:11:58
Subsystem: the rest · Maintainer: Linus Torvalds

Specify some constants in terms of GIT_SHA1_HEXSZ, and convert a
get_sha1_hex into parse_oid_hex to avoid needing to specify additional
constants.
