Something like

	git read-tree HEAD
	git checkout -f

should do it.

The read-tree basically invalidated the index, by forcing it to the HEAD tree (and *without* doing a merge with the old index, so it doesn't get any of the size/date/inode fields right). And at that point, git thinks that all files are stale, so "git checkout -f" will force the checkout for all of them.

I'm sure you can do it other ways too, but that's the "obvious" one.
