  // The line below seems weird, but it is here for a good reason.  In general,
  // text attributes are not null terminated, so you have to add your own (which
  // the std::string will do for us).  However, sometimes a null terminating
  // character is written in the attribute anyway.  In a C string this is no big
  // deal.  But it means that the std::string has a null character in it and it
  // is technically different than its own C string.  This line corrects that
  // regardless of whether the null string was written we will get the right
  // string.
