In the main text we give the pedalling which Chopin added while proofreading FE (→EE). In GE1 the 
mark was omitted, which was added in subsequent GE,s, most probably on the basis of the authentic pedalling in bars 19-20. Lack of the mark in GE1 may be a simple oversight of the edition's engraver or be an echo of the error of the proof copy of FE, corrected in the last phase of proofreading.
