Display problems numbered brackets in new line

[narrenfrei]

The workaround for repeatings and numbered brackets in new lines from #170 results in a not so nice double brackets when there are more than one voice grouped into one staff:

X:1

If you take the second set of repeats off it looks better:

 [|] D z z A :|
 [|] D z F A [|] |

Yes (I already know), but then the generated MIDI file is wrong.

I think your ABC is correct and this is a bug in abcjs for drawing. I've put it on my list, but I'm backed up right now.

I'll accept a pull request is someone wants to look into this.

In the meantime, here's an ugly hack you can use:

renderAbc("paper", abcString, { add_classes: true})
var endings = document.querySelectorAll("#paper .abcjs-ending.abcjs-v1")
for (var i = 0; i < endings.length; i++) {
  endings[i].setAttribute("style", "display: none")
}
