    LICENSES: Clarify wording.
    
    * Say "alternative terms" to characterize works disjunctively licensed
      with the GNU GPL and some other Free Software license, since
      "additional terms" can be misleading in a GPL context (see section 7
      of that license).
    * Stop implying that being in the public domain is a form of license.
      (Rather, it is the absence of a requirement for licensure.)
    
    Also fix a style nit: consistently space after section headings.
