accidentals into account

This can now be worked around in the most recent git.  Same holds true for  
Issue 868.

\score {
  \new Staff { <\parenthesize ais'> }
  \layout {
    \context {
      \Voice
      \override ParenthesesItem #'stencil = #(lambda (grob)
       (let* ((acc (ly:grob-object (ly:grob-parent grob  
Y) 'accidental-grob))
              (dot (ly:grob-object (ly:grob-parent grob Y) 'dot)))
         (if (not (null? acc)) (ly:pointer-group-interface::add-grob  
grob 'elements acc))
         (if (not (null? dot)) (ly:pointer-group-interface::add-grob  
grob 'elements dot))
         (parentheses-item::print grob)))
}}}
