The slurs added in GE2 (→GE3) to grace notes in bars 8, 10 and 12 are definitely conventional in nature. Chopin occasionally wrote slurs of that type for grace notes, e.g. in bar 6, but more often than not he skipped them. In this Mazurka such a slur appears only once, in the said bar 6, and no other grace note slurs can be found anywhere else in A (→GE1→FE→EE), so we do not include them in our main text.
The addition was made in GE2 (→GE3) for all the single grace notes in bars 38, 40, 42 and 44, and in bars 90, 92, 94 and 96, and also for the double grace notes in bar 57 and analog.
