my barline "split arrows" function needs improvement
In the snippet included below, I show how I use angled arrows to indicate a staff will split into multiple staves after the system break.
(Note: It doesn't actually happen here, since I wanted my WE to be reasonably M!)
The problem is, the function attaches the arrows to the carline, which fails in the case of cautionary signatures (see second system). I tried attaching the arrows to the StaffSymbol — that seems the most elegant solution — but my attempt didn't work.
Would love help on fixing this snippet so that it always Does The Right Thing™.
