It is only FE and EE2 that include all slurs linking the grace note with the 1st quaver in bars 85-86 and 89 (the slur in bar 90 is present in all sources). It most probably resulted from Chopin's additions to [FC] or at the stage of proofreading FE1, while in the case of EE2 it was a correction of the oversight in EE1. The versions with a smaller number of slurs resulted from Chopin's inaccuracies in A and from oversights in EE1 and GE.
