Well, ##{ c' d' e' c' #} would work. Basically, almost everything that
is not either a markup or markup list in 2.20 has to start with # .
And I am not sure that the second line will survive eternally: it's
discomfortingly close to markup list syntax and thus would be tricky to
implement once markup commands get more intelligent predicate
interpretation, like music functions do now.
It's conceivable when { gets read to check whether the predicate would
accept '() (the simplest markup list) and only get into music mode when
it doesn't.
Markups are icky things.
