Re: efficient cloning

I think what is reasonable is something like this:

 - If you start from a repository cloned in the traditional
   way, the upstream "master" is kept track of with your
   "origin", so "diff origin master" would be "my changes on top
   of the upstream".

Yes. And it would be nice if the same would work with the new layout,
assuming that there is no local "origin" branch, but a .git/remotes/origin
file and .git/refs/remotes/origin directory.

My primary aversion comes from that I'd rather avoid teaching
the really core stuff about .git/remotes file, and the part that
interprets refname is fairly a low-level part.

We _could_ record refs/remotes/origin/HEAD that points at
refs/remotes/origin/master (or some other branch) upon cloning,
and if Pasky wants to do something similar upon fetching, that
fetch command could do the same thing.
