Re: Trillspan not showing accidental & a problem with its ending

[Graham Percival]

Please create a minimal example.

In particular, I cannot believe that you need an esoteric beam grouping 
for this.  I also can't imagine that the #'script-priority affects 
anything.  Finally, please report one issue per example -- creating an 
example which demonstrates multiple problems is much harder for other 
people to understand.

Cheers,
