Re: warning: forced break was overridden by some other event, should you be using bar checks?

[Valentin Petzel]

Hi Ken,

If you want to have a repeat with no alternative just do not use \alternative. 
Doing \repeat something 0 does not do anything. The repeat-count property 
must be at least 1, if you give 0 it defaults to 1.

Of course doing \repeat volta 1 would also be rather stupid, as this would 
create a repeat that is not supposed to be executed.

Cheers,
Valentin
