Pull up revision 1.43 (via patch, requested by wiz):
  Don't xref set(1) and case(1), since they are builtins and we don't
  have separate man pages for them.
  Xref passwd 5 instead of 4, environ 7 instead of 5, and comment out xref
  to profile(4), which we don't have.
  Improve markup of SYNOPSIS.
  Some whitespace fixes while I'm here.
