The sign at the beginning of bar 3 in A (→FE→GE,EE) may be considered as 
hairpins, especially due to the fact that it is between the staves. However, a comparison with analogous bars 11 and 43 shows that we are probably dealing with an unfortunately placed long accent mark and this is the interpretation we suggest in the main text.
