The four long accents were added to FC by Chopin. In GE1 the first one was overlooked; it is also absent in GE2, in which the adjacent 
was removed too. It may mean that there was an attempt to add an accent, which required to be moved; however, the correction remained unfinished. As accents are also in FE, Chopin most probable wrote them there while proofreading this edition. Reducing marks to the form of common, short accents is frequent in EE and other first editions of Chopin's works.
