In "git pull --rebase" this is used to know the hash of the tracking branch:
. git-parse-remote &&
origin="$1"
test -z "$origin" && origin=$(get_default_remote)
reflist="$(get_remote_refs_for_fetch "$@" 2>/dev/null |
sed "s|refs/heads/\(.*\):|\1|")" &&
oldremoteref="$(git rev-parse -q --verify \
"refs/remotes/$origin/$reflist")"
