And it should serve as the previous measure for starting ties and slurs
and key and meter changes.  And the first measure of the repeat should
serve as the following measure for unfinished ties and slurs for all of
the alternatives except the last one (which means that tie and slur
directions should match and the tie/slur should extend to the bar line
rather than trigger an error).
