  31  *
  32  * Future expansion: split eNormalBreak into multiple priorities, e.g.
  33  *                    punctuation break and whitespace break (bug 389710).
  34  *                   As and when we implement it, text-wrap: unrestricted will
  35  *                    mean that priorities are ignored and all line-break
  36  *                    opportunities are equal.
