Key change in alternative 1

[Malte Meyn]

Hi list,

how should I treat a key change in the first alternative of a volta 
repeat? I’m not sure whether to print the “change back” at the beginning 
of the second alternative (m. 5 of the attached code).

I don’t think it’s necessary to print it if the change coincides with a 
line break (LilyPond’s default behaviour, variant 1 in the attached 
code). But is it necessary when there is no line break (variant 2 or 3)?

And another thing: I added keyAlterations to the alternativeRestores 
context property; shouldn’t this be the default?
