MIDI repetition

[Alberto Manuel Brandão Simões]

Hi
I found
http://lilypond.org/doc/v2.0/input/test/out-www/lily-429032051.ly,
the example for unfolding repeats, and it works (great!)

My question is: if we write repetitions on the music (and if the
composer wrote them) it means we want to repeat them. Why to add a new
command to unfold them? Wouldn't it be better to oposite? (a flag if you
do not want to unfold at all?)

Just my five cents.
