Oh well. The upshot is that you can assume as much
rename/copy/add/delete history as you like, with any optimizations to
access to that history you like, and it doesn't matter. Semantically,
that data + noderev history data doesn't add up to enough to do
reasonable tree deltas. Tree deltas reflect the logical roles of
files -- and those ancestry and tree-rearrangement histories don't
reflect the logical roles of files. So you need something new in the
data model -- such as "logical ID cookies".
