Comment #6 on issue 155 by address@hidden: \parenthesize does not take  
accidentals into account

Bravo! This is very exciting. Just a heads up though, this example seems to  
prefer parentheses that align with spaces rather than lines:

\version "2.15.0"
\score {
  \new Staff {
    % parentheses not included in spacing calculations
    \override Voice.NoteColumn #'X-extent = #'(-10 . 10)
    <\parenthesize ais'>4. <\parenthesize bes'>
  }
  \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)))
    }
  }
}
