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

[Ole V. Villumsen]

Furthermore, for the record, the same trick also works in the case where there 
is no break after the end-repeat sign. In this case the second of the three 
inner lists in Score.BreakAlignment.break-align-orders governs the order. So I 
want to modify both the 1st and the 2nd list. From the documentation:

> This is a vector of 3 lists: #(end-of-line unbroken start-of-line).

Having different scores and parts of the same music I now end up with clearly 
more readable and sensible Lilypond source than I had before. And nicer typeset 
music. Hallelujah, as Mr. Handel wrote.
