Re: grace/appoggiatura slur problem

[Erik Sandberg]

I would consider this a release-critical bug; in some situations it looks very 
strange. I have lost cvs write access, so it isn't added to cvs. Here it is:

%critical
%David Bobroff

\version "2.5.24"

\header {
 texidoc = "Appoggiatura slurs are ugly sometimes when changing stem 
directions."
 reportedin = "2.5.24"
}

\relative {
 \stemUp \appoggiatura {f16-[ g a-]} \stemDown a4
 \stemUp \appoggiatura {f16-[ g a-]} \stemDown  b4
 \stemUp \appoggiatura {f16-[ g a-]} \stemDown c4
 \stemUp \appoggiatura {f,16-[ g a-]} \stemDown d4
 \stemUp \appoggiatura {f,16-[ g a-]} \stemDown e4
}
