Incorrect unfolding if a jump is to happen only the third time [BUG]

[johentsch]

Take this example
incorrect_unfolding.zip

measure	1	2	3	4	5	6	7
jump		𝄋	|:	to 𝄌	:|	D.S. al Coda	𝄌

Expected unfolding

1 2 3 4 5 3 4 5 6 2 3 4 7

Actual unfolding

1 2 3 4 5 3 4 7

Suggested solution

The next column for m. 4 needs to read 5 5 7 rather than 5 7.
If the pointer hits an end-repeat (m. 5) everything repeated bar could get its next bar prepended. Or only "non-default" bars, such as m. 4 in the example.
