I don't think that's meaningful. You need a revision history to do a delta,
otherwise you can't know which is the "previous" revision (you can use left-most
parent, but that's arbitrary). Consider 2 branches A and B: first, in A you
merge B and commit, then in B you pull A. Both branches now have the same
"head" revision, but they have different revision histories. In particular, the
"head" revision has a different predecessor in A and in B.
