Also, one gotchya is that for this to kick in, alternatives must be 
contextualized in curly brackets.  So,

\repeat volta 4 { a1 } \alternative { a b }

Will never work with the current AlternativeEvent implementation, whereas

\repeat volta 4 { a1 } \alternative { { a } { b } }

will.

It is not impossible to add the AlternativeEvent in 
Volta_repeat_iterator::get_music_list (), which would get around this problem.  
But it'd be doing a lot of event-management at the iterator level, which is so 
far as I know hitherto unprecedented.  Any thoughts?
