  * Support qualified identifier names in the Haskell parts of hat-observe
  and hat-trail.
    * There is a new option ":set qualified" to choose whether to display
      all names qualified or not.
    * Qualified names are parsed in hat-observe patterns, but the
      C back-end machinery is not yet written to ensure that only the
      selected identifier is actually observed.
