If it's clumsy, it's because this workflow is clumsy in a proper DVCS anyway. The usual way to find where a changeset has gone is to see where it's been *merged*.

That being said, as Pierre-Yves mentioned, there is the 'destination(REV)' revset that will give you all the changesets created by grafting REV:

    hg log -r 'destination(deadbeefd00d)'
