It's sort of misleading because origin is not the origin, it's your copy of the origin. You have to fetch to make it the same. I can't suggest a better name,

It's sort of misleading because origin is not the origin, it's your copy of the origin. You have to fetch to make it the same. I can't suggest a better name, but you have to admit the word 'origin' suggests the origin, not some partial copy of it. It's not a biggy, it's just one of the little toe-stubs and paper cuts you get over pretty quickly.
