Regularise use of repeats, tune (A/B/C etc.) markers and final bar. 1. Only show tune markers when a tune change is in the middle of a line. 2. Only show repeat starts |: if the repeat start is in the middle of a line. 3. Final bar end mark must be a thick line. The official rules for a repeat are that if there is no left repeat marker |: then the repeat starts at the previous double bar.
