The divided slur in the sources is, according to us, a result of an inaccurately drawn extension of the slur in A. Initially, the slurs embraced only the irregular groups on the 4th crotchet in bar 84 and in the 2nd half of bar 85. Chopin then extended the first of the slurs, but he did not drag him to the beginning of the second one. In an analogous situation in bars 92-93, A combined the slurs in an unquestionable way. (Cf. also continuous slurs in bars 83 and 91).
