The thing is that in the visual layout, repeat voltas are not
represented by any actual repetitions but by repeat barlines and similar
stuff.  So it is sufficient to add the volta/repeat structure to one
Staff/Voice/whatever.

However, \unfoldRepeats does not work at the music "iteration" stage but
changes the music expression directly.  So its effect does not extend to
\harmonies .

You need to place the volta/repeat structure in every Staff/Voice to
have \unfoldRepeats do its work successfully.
