AccidentalSuggestion and avoid-slur

[Simon Albrecht]

Hello,

if both an AccidentalSuggestion and a slur are attached to a note, 
LilyPond places both as expected, but issues a warning about avoid-slur 
not being defined for AccidentalSuggestion. The appropriate solution 
would probably be to just insert a line (avoid-slur . around) [the 
latter probably being the adequate value] as a first entry for the 
definition of AccidentalSuggestion in define-grobs.scm .
Let me know if you need any examples of this.
Best regards

Simon Albrecht
