Introduce <branch>@{upstream} notation

A new notation '<branch>@{upstream}' refers to the branch <branch> is set
to build on top of.  Missing <branch> (i.e. '@{upstream}') defaults to the
current branch.

This allows you to run, for example,

	for l in list of local branches
	do
		git log --oneline --left-right $l...$l@{upstream}
	done

to inspect each of the local branches you are interested in for the
divergence from its upstream.
