Log Message:
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.
