  + Set page topics in italics, not bold.
  + Add section number to first occurrence in page of non-groff man
    page cross-references.
  + Where they are command-prefixed at build time, lead them with a
    hyphenation suppression escape since we cannot know whether the
    user's choice for the prefix will cause a hyphenation event.  Also
    suppress hyphenation if the page topic could otherwise experience
    it, and stop suppressing hyphenation if it couldn't.  Going ahead
    and implementing .MR is looking better and better...
