Some index-base bug in "next" branch ("git-applymbox"-related?)..

Junio, I've been running "next", because of working on the submodule 
stuff.

I  just did some trivial kernel stuff: applied seven patches, and tried to 
do a "pull". And whoa, that failed. I get this:

	[torvalds@woody linux]$ dotest ~/doit
	7 patch(es) to process.

	.. all apply fine ..

	[torvalds@woody linux]$ git pull master.kernel.org:/pub/scm/linux/kernel/git/galak/powerpc.git for_linus
	remote: Generating pack...
	...
	Unpacking 22 objects
	 100% (22/22) done
	Your index is based on '80584ff3b99c36ead7e130e453b3a48b18072d18' commit, but the branch tip you are on is at '6a04de6dbe1772d98fddf5099738d6f508e86e21'

That "80584ff.." commit is the commit *before* the "dotest", and HEAD is 
(correctly) 6a04de.. that is the end result of the "dotest". That "dotest" 
thing is just because "git-applymbox" isn't in my brain stem:

	[torvalds@woody linux]$ alias dotest
	alias dotest='git-applymbox -u'

so it's not actually anything strange.

Doing a "git reset" obviously fixed it, but if I didn't know that you had 
been working on that "index BASE" thing, I would have been very worried.

That index base thing is definitely *not* ready for merging into master 
yet!
