  Correct logic for filling out a "new" label during a credential
  change in mac_lomac: if both flags are set on the new label, we
  may not need to always fill out the label (only if one flag is
  set, not both).  Avoid stomping on a section of the label if we
  are in fact modifying both elements.
  Because we know that both flags will be set, we don't need to
  test whether the range or single are set in later consistency
  checks of the range and single -- just test them.
  By checking the range of the new vs. the range of the old label
  before testing the single against the new range, we implicitly
  test that the new single is in the old range.  Document this
  with a comment.
