# XXX The comparison is broken because of the new original

# by normalizing those comments (like replacing the object
# IDs with nnn) and then diffs. That will work here and
# in some of the other failure cases. For the rest where
# we're actually checking the qdf itself, we will need to
# store the new qdf files with the object IDs. That can't
# be done blindly -- we need to make sure the output is
