[trunk] R4786 New 'Save Selection' feature
This is an good feature, but it has some interesting limitations or side-effects. If you select only one staff of a two-stave system (piano score) and Save Selection, the resulting score has the correct time/key sig in the correlating staff, but the other staff is a no-mans land (blank, no time/key sig). No notes can be added and attempts to drop time/key sigs made MS crash. There's also not a correct ending bar line at the end, but thats not important. I didn't notice anything else yet.
It would seem appropriate to populate the empty staves with the correct time/key sigs and rests and putting the correct ending bar line at the end.
