Recursive percent repeats

[Erik Sandberg]

Hi,

I have half a bar of music which is repeated 6 times, and I'd like the output 
to look something like

| [music] / | % | % |

The intuitive way to do this would be
\repeat "percent" 3 {
  \repeat "percent" 2 { [music] } |
}

but I just get a "warning: no one to print a percent" and the "/" in the 
first bar is not output. Using 1.4.12. Is this fixed in 1.5? How should I do 
to get the desired result?
