Best-of-five match decided after the wrong number of sets · case 02
A best-of-five match is declared over while a player has only two sets.
Case contract

The match ends when a player has won best_of // 2 + 1 sets; later games are ignored. Return [set scores as "a-b" strings in A-B order, match winner or None]; an unfinished set with at least one game is appended as its current score.
