afterGrace and slashedGrace

[Federico Bruni]

I think that I already asked the same question few weeks ago but can't find it in my inbox nor in the archives.

How can I use slashedGrace for a grace note at the end of a bar?

\version "2.19.15"

\relative c'' {

  \slashedGrace d8 d4 r2. |

  \afterGrace c1 { d8 } |

  

  % the grace note is printed as normal note (bigger) and without the slashed stem

  \afterGrace c1 { \slashedGrace d8 } |

}
