A vertical slur written in A before the c2-c3 octave designates an arpeggio: it is just a simplified form of the standard wavy line, cf. e.g. the last chord in the 3rd movement, bar 484. In that period of Chopin's life the simplification process had just begun, hence a misunderstanding of this notation on the part of engravers is understandable.
