octave: Block Comments

 
 2.7.2 Block Comments
 --------------------
 
 Entire blocks of code can be commented by enclosing the code between
 matching ‘#{’ and ‘#}’ or ‘%{’ and ‘%}’ markers.  For example,
 
      function quick_countdown
        # Count down for main rocket engines
        disp (3);
       #{
        disp (2);
        disp (1);
       #}
        disp ("Blast Off!");  # Rocket leaves pad
      endfunction
 
 will produce a very quick countdown from ’3’ to "Blast Off" as the lines
 "‘disp (2);’" and "‘disp (1);’" won’t be executed.
 
    The block comment markers must appear alone as the only characters on
 a line (excepting whitespace) in order to be parsed correctly.
