\parenthesize ??

[luis jure]

in the manual i find: "Objects may be parenthesized by prefixing
\parenthesize to the music event."  but when i compile the example in
the manual i get no parenthesis. the following code gives the output
attached:

\version "2.11.43"

\layout {
ragged-right = ##t
}
        \relative c'' { 
                c2 \parenthesize d
                c2 \parenthesize <c e g>
        }


i tried with both 2.11.42 and 2.11.43. is \parenthesize not working, or
am i missing something?

best,

lj
