Re: Clef change after end-repeat before break -- how?

[Ole V. Villumsen]

Thanks, everyone, for your contributions.

First of all Jean. Your code gives me exactly what I wanted. I haven’t learned 
to use the internals, but see here that it’s useful.

I am skeptical. There’s no separate measure there.
When I move the setting of the measure position to later in the bar,
I still get the same space (but then not the measure number, 5,
on the 2nd line, which makes sense). So still curious.

That’s still more curious. On 2.22.2 I get a warning
that the break is overwritten by another event, so we
don’t get the line break that I had specified and wanted.

@Ralph Palmer, you may have forgot to put content into your message? At least 
none arrived here.

Best, Ole
