Slur to crotchet G in sources

Slur to C suggested by the editors

In the main text we give a slur resulting from the changes introduced by Chopin to FC, striving at integrating the beginning of the Mazurka main theme, that is the 1st beat of bar 101, with the preceding four-bar section, in particular the change of the chord to a single note, closing the bass line, and the extension of the R.H. slur. According to us, the fact that Chopin did not explicitly mark such an extension in the L.H. part is an oversight in the implementation of this wide-ranging change.

Chopin added  to FC (→GE1). It was removed in GE2, perhaps due to a misunderstanding during revision – see the adjacent note.
