  Modified files:
    usr.bin/tar          getdate.y 
  Log:
  Overhaul getdate.y.  In particular, remove minutes-based logic
  (combine with existing seconds-based), treat '-' as punctuation rather
  than a negative number indicator (eliminates several special cases),
  use a single list of special words instead of several separate lists,
  use table-driven abbreviation logic (eliminate duplicate word entries
  and special-case abbreviation and plural handling).  The result is
  shorter, simpler (judging from comments, earlier maintainers didn't
  understand the special handling for "negative years"), handles more
  cases (e.g., "tu" is now a recognized abbreviation for "tuesday",
  "3rd" is now equivalent to "third") and it has 2 fewer shift/reduce
  conflicts.
