Oh, I'm blind. I didn't see git-checkout-index, (thanks Kenneth for
mentioning it elsewhere in the thread). So now I've at least got the
recipe I was after:

	git-read-tree <revision>
	git-update-index --replace
	git-checkout-index -a -f -u

This is very very inefficient, because it will replace the old 
index without using the (valid) information that is there from before. 
Resulting in a lot of unnecessary IO..

You may not care for a small project, but for bigger stuff, you're better 
off using more subtle approaches.

Explore using "git-read-tree --reset <revision>" or, perhaps even more 
interesting is "git-read-tree -u -m <oldrev> <newrev>"

And I think that would make for a dandy command to have in git. Any
suggestions for a name?

I'd suggest "git reset" as a cool way to say that it "resets" the tree to 
another version ;)
