   In addition, 'c_str() const' should return an array that terminates with   
   a null character (charT()), and 'operator[](size_type pos) const' should   
   return charT() for pos == size(). Therefore, I think an implementation   
   that doesn't keep a null character at the end is making things difficult   
   for itself for no good reason I can see. (Let me know if there are some.)
