..

As far as the naturals raising e to e in the 2nd half of bar 255 are concerned, in A Chopin was satisfied with accidentals to the L.H. chord (e1) and the 3rd demisemiquaver (e3). The remaining 3 naturals necessary later in the passage were added by GE (→FE,EE).
In EE the  to the L.H. chord, which was placed slightly too low in GE1, was interpreted as a natural raising d1 to d1.
In A the  to e3 is written too low, at the pitch of c3. Such inaccuracies are often to be found in Chopin's autographs, generally – as is the case here – with no influence on the interpretation of the text.

Shorter slurs in Af

Various slurs in A

Longer slurs in GE (→FE,EE)

In the main text we reproduce the clearly written slurs of A, although it is uncertain whether by differentiating the range of these slurs Chopin really wanted to suggest a detail of articulation. Both remaining, unified versions of slurring can be regarded as equivalent variants.

The  hairpin is written in A between the staves and begins after the 1st R.H. chord (in Af the bottom arm starts as early as at the beginning of the bar). In GE (→FE,EE) the mark was moved to over the R.H. part, which, in this case, does not significantly influence its meaning. The change was most probably forced by lack of space between the staves; it cannot come from Chopin. The slight change of range in GE1 (→GE2) – the beginning of the mark was moved slightly to the right – was intensified by all subsequent editions, while FESB additionally reversed the direction of the mark, which is a frequent mistake in the first editions of Chopin's pieces.

2 staccato dots in A

Wedge in GE1 (→FE,GE2FESB)

2 wedges in EE

3 wedges in GE3

..

In A the staccato marks over the bass G notes are clearly dots in this bar, and not wedges, as was the case before and as was conveyed by GE and the remaining editions. It was not an inaccuracy of notation, since in both places one can see traces of corrections (erasures). In the next bars, the bass notes are not marked staccato at all, which may suggest that the articulation should get gradually longer (milder?) as the modulation progresses and as the music calms down.
The absence of the second mark in GE1 (→FE,GE2FESB) probably resulted from an oversight (or the engraver was uncertain which mark to apply). The additions in EE (the 2nd wedge in bar 268) and GE3 (the 2nd wedge in bar 268 and the wedge over the first F in bar 269) were arbitrary decisions of the revisers.
