I would omit this check - parse_oid_hex already exits early if the first
character is NUL. (The existing code makes a bit more sense, in that it
avoids checking the first few characters if we already know a bit more
about the string.)
- if (get_sha1_hex(line->buf, sha1) < 0)
+ if (parse_oid_hex(line->buf, oid, &ref) < 0)
return NULL;

Looks fine, up to here.
(Also, you requested extra-careful review for this patch, but this patch
seems mostly mechanical to me.)
