Sometimes the easiest way of using these repeat constructions is to
copy and paste an example from Notation Reference ยง1.4 into your
.ly file, and then insert your music in place of the example's.
If you have a repeat structure nested in another, you can cut and
paste a second example at the appropriate point, and then replace
the music (or placeholder text) in the example with your music again.
However, the example given above doesn't have nested repeats, but
overlapping ones. LP has a mechanism for distinguishing which repeat
an \alternative belongs to if two repeats are nested (it chooses
the innermost). But there's no LP mechanism AFAIK that can unpick
two overlapping repeat structures, so a manual solution is required,
as given.
