Pure pedantry: Replace all ".size() == 0" with ".empty()".

Nit: Eliminate anonymous namespace of consts and collapse to:

  if (!eol.empty()) {
    if (eol[0] == '\n')
      return 1;
    if (eol[0] == '\r')
      return ((eol.size() > 1) && (eol[1] == '\n')) ? 2 : 1;
  }
  return 0;

     return 0;
   }
   if (eol[0] == kLinefeed) {
     return 1;
   }
   if (eol[0] == kCarriageReturn) {
     if (eol.size() > 1 && eol[1] == kLinefeed) {
       return 2;
     } else {
       return 1;
     }
   }
   return 0;
 }
 }  // end namespace o3d
