Comment #2 on issue 1356 by percival.music.ca: LilyPond-style comments  
embedded in a Scheme expression can't include special characters
http://code.google.com/p/lilypond/issues/detail?id=1356

So the "documentation bug" is that instead of writing "the $ character may  
be used to introduce scheme forms", it should say "the $ character means  
that a scheme form follows, even in a lilypond comment.  To use a literal $  
anywhere, including a lilypond comment, you must use $$."

?  in other words, the "may be used" is unclear, since it suggests that  
it's not required?
