Log:
  MFC r332421: vt: add three more cp437 mappings for vga textmode
  
  In UTF-8 locales mandoc uses a number of characters outside of the Basic
  Latin group, e.g. from general punctuation or miscellaneous mathematical
  symbols, and these rendered as ? in text mode.
  
  This change adds (char, replacement, code point, description):
  
      – - U+2013 En Dash
      ⟨ < U+27E8 Mathematical Left Angle Bracket
      ⟩ > U+27E9 Mathematical Right Angle Bracket
  
  This change addresses some common cases; there are others that still
  need to be added after a more thorough review.
