Sforzando not handled correctly in midi /ChangeLog/1.3553/

[Bernard Hurley]

Hi,

A problem with ChangeLog/1.3553/, but I think it occurred in earlier
versions of lily too.

The code:

\score {
  \new Staff {
    c c\sfz c
  }
  \midi {\tempo 4=72}
}

results in a midi file with a control-change event 7 (main volume) with
value 63 inserted before the second note. This has the effect of
reducing the volume of the second two notes.
