The snippets are not public domain, unless the author put them there.
The *music* may be public domain, but the *arrangement* is copyright
whoever wrote the lilypond code (unless you make the argument that the
snippet is too small to qualify for copyright).
The snippets are taken from the LSR and a condition of submission to the
LSR is that you consign your work to the public domain (and that you
have the right to do so). I know, because I submitted a couple of
snippets to the LSR and they later made it into the Lilypond docs'
selection of snippets.
