It sounded like Robert was suggesting making a _real copy_ of the
_whole_ tree, way more inefficient than a full inventory (which are
actually pretty cheap these days).

I suspect that even the full inventory isn't necessary in many common
cases either (e.g., a simple list of filenames that haven't been renamed).
