None of the sources provides correct pedalling in these bars. No 
in EE (b. 632) and FE (b. 634) may only slightly mislead the performer as in both sources the moment of releasing (changing) pedals is marked with 
(accordingly in bars 633 and 635). In GC (→GE) there is no pedalling until the end of the piece, which most certainly can be classified as the copyist's omission (in two last lines of the text 259-266 i 548-553).
