Re: box-grob-stencil

[Mats Bengtsson]

I don't know exactly why it gives a stack overflow, but here are some
hints:
- print-function is normally undefined from the System object,
  whereas NoteHead already has a print-function that typesets
  the note head, which you probably want to keep as well.
- Take a look at the example called boxed-stencil.ly in the
  Tips and Tricks document.
