New here and first question about using repeat percent over more than two measures

[Aurelien]

Hi,

I'm new on this list, though I use Lilypond for several years (but quite
basically) and audio with GNU/Linux for more years.

I present myself: I'm Aurélien, I'm french, work in a french non-profit 
production/label/tour agency which produces and tours only free art with 
free software.

I play bass, guitar, machines and vocals in the band Sebkha-Chott, and
also play in a musical tales for kids called Sackboutboute.


OK, let's go with my question. As I'm also a bass teacher, I often use
\repeat precent X {} in my scores. Until now, I never had any problem
with this. But now, I've got two charts with stuffs repeating that long
more than two measures. I thought I just could write something like:

\repeat percent X {
        <first measure>
        <seconde measure>
        <third measure>
        <fourth measure>
}

but actually, it just prints empy measures in the end. Is there a way to
fix this, or am I trying to do something that doesn't exist, or
shouldn't, or whatever?

Thanks a lot.
