Sorry, I was unclear. But doesn't that imply that a SCM built
on top of git storage needs to read all the commit and tree
records up to the common ancestor to show tree diffs between two
forked tree?

I suspect that another problem is that noticing the move of the
same SHA1 hash from one pathname to another and recognizing that
as a rename would not always work in the real world, because
sometimes people move files *and* make small changes at the same
time. If git is meant to be an intermediate format to suck
existing kernel history out of BK so that the history can be
converted for the next SCM chosen for the kernel work, I would
imagine that there needs to be a way to represent such a case.
Maybe convert a file rename as two git trees (one tree for pure
move which immediately followed by another tree for edit) if it
is not a pure move?
