Hi Massimiliano,
the code you provided is _very_ old. I modified it a bit in order to
work with both possible stem directions and respect rests. Also, there
was a hard-coded offset for the cross that can more succinctly be
replaced by a \center-align.
I also lenghened the stems a bit. Note that this does not work together
with beams - I suspect it's got to do with unpure-pure-containers, which
I don't understand :-).

And another possibly outrageous question… when I invoke /\sp/, it
works from the first following note on to the last note, rests
included (!).
How do I stop it?
I showed both \undo\sp and \once\sp in my example.
Enjoy LilyPond - it's amazing what you can achieve with it!
