Yeah, I agree with this. In particular, the code has already been
modified to use "struct object_id" and parse_oid_hex(). So it is not
even like somebody will have to come through later and fix the
implementation here, and while they're at it change the "SHA-1" in the
message. It has literally already been fixed, and is just waiting on
parse_oid_hex() to learn about the new hashes behind the scenes.
IMHO the conversion to object_id probably would have been the time to
fix that message so we would not even have to be revisiting the
discussion now. But that conversion was such a monumental pain it is
hard to fault the authors for not picking up every scrap at that moment. ;)
That is no excuse not to do it now, though.
