Slurs broken 2.1.27 DrumStaff

[Bruce McIntyre]

Hi.

Inside a DrumStaff or a DrumVoice, both Slurs and PhrasingSlurs don't
work: they result in "Junking event" warnings.

This also means that appoggiaturas die too.  Drummers use these alot
 (we call them flams or ruffs)

Cheers, Bruce.


slurtest = \drums {sn4\(  sn4\) sn4( sn4) |
                \appoggiatura{sn16[ sn16]} sn4 }
\score { \new DrumStaff <<
  \new DrumVoice {
                  \slurtest
                 }
  >>
}
