Sorry, it does not really.

The patch deals with the above sequence correctly, but it breaks
down with:

	echo frotz >infocom
        git update-index --add infocom
        echo xyzzy >infocom
        sleep 3 ;# a little while later
        echo nitfol >activision
        git update-index --add activision
        git diff-files infocom

We need to detect the false clean entries just before we write
out index in the second update-index and mark them out of date.
