The first \slurUp is the one which is wrong, probably another issue #13
related bug but I'm not sure how.
Well, at least I knew there was something going on somewhere …
Acciaccature are governed by grace modes and have their own notion of
slur direction. You have to write
\acciacatura { \slurUp c8 }
to have the \slurUp count for the acciaccatura (or other grace notes).
I was not aware of that, thanks!
