Ouch. Looking at the relevant code path uncovered what
is to me buggy-looking behavior.

So, yes, "and" would be a good idea.

The two universally accepted values for any property
regardless of the predicate are #f and '(), so it
may still be '(), which is why checking with specific
predicates like this is often used in LilyPond's
source.
