Btw, if it wasn't clear, with this patch you can now do

	git diff .

and it will show the diffs for everything under the current working directory. Similarly, you can do

	git diff ./drivers

or something like

	cd arch/i386
	git diff . ../x86-64

and it will do the obvious thing (the "obvious thing" in the latter case is to show the diffs for everything under _both_ arch/i386 and arch/x86-64, but not anything outside of that - the path pattern gets rewritten to "arch/i386" and "arch/x86-64").

PS. A number of the other "work tree" ops can be similarly extended to DTRT in git project subdirectories, but I wanted to finish off the "git diff" family first, and get that one all done. I think I'm done now, and I might tackle the other things (git-update-cache, git-checkout-cache, git-commit-script, etc) tomorrow.
