In EE the accents in the first four bars, just like in the practically entire piece, are short. It is an arbitrary change of the revisers. Long accents, most probably written by Chopin in [A], are present here only in FE. The first three accents of GE introduce a certain ambiguity, since their typeface is slightly different (they are narrower) than of the remaining marks in this source – perhaps they are also supposed to be interpreted as long.
