Comment #19 on issue 1110 by address@hidden: Wrong octave of repetition chord  
with \relative and #{ #} syntax
http://code.google.com/p/lilypond/issues/detail?id=1110

I've made a minimal proof-of-concept sketch on  
<URL:http://codereview.appspot.com/5286048>.  It only works on music  
sequences, and it does not attempt to carry the last chord information  
across a sequence.  As a consequence,  
input/regression/repeat-tremolo-chord-rep.ly fails.

To do this properly, one would have to carry the chord info across  
sequences and elements in a similar manner that the last pitch is carried.   
In particular, this would necessitate splitting out this functionality from  
music_list_to_relative into a separate function  
music_list_to_chord_relative (so that it can accept and return a reference  
chord like music_list_to_relative accepts and returns a starting pitch).

It would also need to pepper the various music items with callbacks and/or  
implement a more elaborate default behavior for the chord callback  
(currently just a nop).

In short, a solid body of grindwork.  Let's see whether any of those that  
declare q worth of fixing will actually contribute anything to make it  
happen.
