Why can't you use safe with predefined fretboard diagrams? Is it just
because addPredefinedFretboard isn't a safe function? If so, I think we can
just make addPredefinedFretboard a safe function; I believe it won't accept
arbitrary scheme. But maybe it will take some work.
DON'T PUT LILYPOND UP ON A WIKI WITHOUT USING --safe. It is a *HUGE*
security risk, because you can execute arbitrary scheme code in lilypond to,
for example, erase the hard drive of your system. At least, that's my
opinion.
