The absence of the slur in both versions of GE1 means that most probably it was originally absent in FE too, in which, however, it was added – probably by Chopin – in the last phase of proofreading. The slurs added in later GE, embracing two full bars, are a result of a revision, same as in bars 10-11. In turn, an earlier beginning of the slur in EEC may be simply an inaccuracy.
