LSR Snippet 318

[Malte Meyn]

Hi list,

I’m not sure where to post an LSR bug report but maybe the people 
responsible for the LSR read this list?

Snippet 318 (http://lsr.di.unimi.it/LSR/Item?id=318) states that 
\parenthesize for notes works only inside chords. That’s not correct, 
the following works as expected in 2.12.3 and newer versions (I haven’t 
tested older ones):

{
  a
  \parenthesize b
  \parenthesize <c'>
  <\parenthesize d'>
}
