I don't want this behaviour for my purpose but if you do want a rest for indexes out of range, you just have one line to change in the code.

 

First make sur you have the latest version of chord.ly at

http://gillesth.free.fr/Lilypond/chord/

 

Change the line 39

  ((null? res) (list-ref notes (1- len))) ; last note

 

by that

 

((null? res)

       (let ((note (list-ref notes (1- len)))) ; last note

            (make-music 'RestEvent

                                    'duration (ly:music-property note 'duration))))

 

You'll get the joined image
