Help with accaciatura

[Alberto Simões]

Hello

In a piano piece, I have an accaciatura in the beginning of a repeat, in 
the upper voice.

In the lower voice, it does not exist.

It seems lilypond is somehow confused by it.

You can see the pdf here:

And if you have the patience, the code is

Lower voice here:

Upper voice here:

https://github.com/ambs/music/blob/master/Gounod/ValseDesSylphes/valse.ly#L37

Sorry for the links for github. I hope it can make it easier. If not, 
I'll try to do it other way.

Thank you
Alberto


PS: when I end transcribing, I would be grateful is someone offer to 
proofread, and if someone else (or the same volunteer) would be kind 
enough to help with the rendering quality. If you are willing to do 
that, let me know. Work will be available in a CC-3 ShareAlike license,
