b. 28

composition: Op. 28 No. 8, Prelude in F♯ minor

  in A (→FEEE)

No signs in FC (→GE)

..

The missing dynamic hairpins in FC (→GE) are a patent oversight of the copyist.

The  mark in A is clearly shorter than the respective one in analog. b. 28, hence one could interpret it as a long accent. According to us, it is more likely that, in the face of the preceding it  mark, Chopin meant a diminuendo hairpin. In the main text we keep the slight difference in the range of the marks between those bars, visible in A. Both FC (→GE) and FE (→EE) clearly extended the  marks, whereas FC (→GE) also shortened the  mark.

b. 31-32

composition: Op. 28 No. 8, Prelude in F♯ minor

Continuous slur in A (→FCGE)

Separate slurs in FE (→EE)

..

The division of the slur between the bars must be a mistake of the engraver, probably misled by the shortness of the bars in A, written in an abridged manner.

b. 32-33

composition: Op. 28 No. 8, Prelude in F♯ minor

Separate slurs in A (contextual interpretation→FCGE)

Continuous slur in A (literal reading→FEEE)

..

Looking at the notation of A, one can have doubts whether in b. 33 Chopin wanted to continue the preceding slur or start a new one. The change of texture and the  mark, emphasizing the minim chord, are arguments for starting a new slur.
