Bring over improvements from FreeBSD.

  List all of the assignment operators explicitly, for those who have
  been traumatized by perl.

  Add C++ operators (from Christoph Mallon <christoph.mallon%gmx.de@localhost>)

Markup improvements to make PostScript output pretty.

Bring back FILES section now that /usr/share/misc/operator is
resurrected.
