(de)crescendo terminated with (de)crescendo doesn't afftect midi volume

[PrzemysławPawełczyk]

Hello.

I spotted this bug 2 months ago. Was easy to workaround, so I forgot to
notify about it. Affects both stable and dev branch.


%\version "2.14.2"
\version "2.15.26"

global = { \key c \major \time 4/4 }
rightHand = \relative c' { \clef treble c8 d e f g a b c \bar "|." }

dynamics = { s4\p\< s4  s4\> s8 s8\! }
% crescendo doesn't work in midi unless it's terminated with explicit \!
% (like the following decrescendo here)
% there is no problem if you use absolute dynamic to terminate, though

\score {
        \new PianoStaff = "piano" <<
                \new Staff = "up" << \global \dynamics \rightHand  >>
        >>
        \midi { }
}


Regards.

P.S. Please add me to CC as I'm not on the list.
