Odd code in flags.cc

[Phil Holmes]

 bool adjust = true;

 string staffline_offs;
 if (flag_style == "mensural")
   /* Mensural notation: For notes on staff lines, use different
      flags than for notes between staff lines.  The idea is that
      flags are always vertically aligned with the staff lines,
      regardless if the note head is on a staff line or between two
      staff lines.  In other words, the inner end of a flag always
      touches a staff line.
   */
   {
     if (adjust)
       {
         int p = (int) (rint (Stem::stem_end_position (stem)));
         staffline_offs
           = Staff_symbol_referencer::on_line (stem, p) ? "0" : "1";
       }
     else
       staffline_offs = "2";
   }
 else
   staffline_offs = "";

Not convinced staffline_offs is ever 2?  I believe essentially the same code 
is in flag-styles.scm.
