Fw: Parenthesizing rests

Ah - I should have added you need to introduce the new \parenthesize command as an articulation when you need to parenthesize a dynamic or markup, like this:

a -\parenthesize \pp

Hi Reinhold

This is really good! One addition (at least) is needed, though. To parenthesize dynamics you need to add

            (memq 'absolute-dynamic-event (ly:music-property ev 'types))

to the 'or' clause.

I would say that only mapping it to notes and rests is better.  If
the user really wanted articulations parenthesized, he could write
  \parenthesize c4 \parenthesize -.

Okay, then the parenthesize function gets a little bit longer:
parenthesize =
#(define-music-function (parser loc arg) (ly:music?)
  (_i "Tag @var{arg} to be parenthesized.")
  (if (memq 'event-chord (ly:music-property arg 'types))
      (lambda (ev)
        (if (or (memq 'note-event (ly:music-property ev 'types))
          (memq 'rest-event (ly:music-property ev 'types)))
          (set! (ly:music-property ev 'parenthesize) #t)
      (ly:music-property arg 'elements))
    (set! (ly:music-property arg 'parenthesize) #t)

An example including that code is attached, will submit it to the LSR in the
near future.
