Verbal indications

b. 42-45

composition: Op. 28 No. 16, Prelude in B♭ minor

cresc. - - - till bar 45 in A & FE2 (→EE)

No indication in FC (→GE)

cresc. - - in bar 42 in FE1

..

In the ending of the Prelude Fontana overlooked a few various performance markings; in addition to cresc. - - - , it was also  and  the L.H. slur in b. 40-41, the accent in b. 42, the staccato dots at the beginning of b. 40 and at the end of b. 45 and  in b. 45. No further dashes in FE1 is an oversight of the engraver, corrected in FE2 (in accordance with A).

b. 45-46

composition: Op. 28 No. 16, Prelude in B♭ minor

 in A (literal reading→FE1)

 in A (contextual interpretation→FE2EE)

No marking in FC (→GE)

..

The  mark is placed in A between the pair of the final chords, hence the fact that FE1 assigned it to b. 46 is formally justified – markings are not retroactive. However, it seems much more likely that Chopin applied here the manner of writing indications within the scope of their range, and the mark is supposed to concern both chords, as it was performed in FE2 (→EE). Cf., e.g. the Concerto in E Minor, Op. 11, 1st mov., b. 16.
