b. 158

composition: Op. 35, Sonata in B♭ minor, Mvt II

 on 2nd beat in GC (→GE)

 on 1st beat in FE (→EE)

It is hard to state which of the sources guessed the sense of the notation of [A] more accurately. It is highly likely that even seeing the autograph, we would not be sure how to assign the  sign, as in the case of the lower placed notes, Chopin would often put these signs before the note and not under it, which sometimes resulted in ambiguities. In the discussed bar, both pedalling versions are possible; to the main text we adopt the less schematic version. The absence of  in GC is a patent oversight.
Similarly in bar 159.

b. 158

composition: Op. 64 No 2, Waltz in C♯ minor

..

GE2no2 overlooked the pedalling in this bar, perhaps in order to unify this bar with bar 30.

b. 158-159

composition: Op. 35, Sonata in B♭ minor, Mvt I

1 accent in GC

b. 158

composition: Op. 21, Concerto in F minor, Mvt I

..

In A Chopin overlooked two naturals necessary on the 4th quaver in the bar (a and e1). GE1 (→FEEE) added a  raising a to a. GE2 has the correct text.

b. 158

composition: Op. 11, Concerto in E minor, Mvt I

Minim in FE

Dotted minim in GE & EE

..

A comparison with similar bars 160, 513 and 515 points to a very likely oversight of the dot extending the f minim in FE.
