Coincidentally, I had the same problem the day before yesterday. Here is
what I have (using the \parenthesize command and modifying its behavior):

%%%%%%%%%%%%%

#(define-public (parentheses-item::calc-parenthesis-left-stencils grob)
  (let* ((font (ly:grob-default-font grob)))
    (list (ly:font-get-glyph font "accidentals.leftparen") empty-stencil)))

#(define-public (parentheses-item::calc-parenthesis-right-stencils grob)
  (let* ((font (ly:grob-default-font grob)))
    (list empty-stencil (ly:font-get-glyph font "accidentals.rightparen"))))

parenthesizeLeft = #(define-music-function (parser loc arg) (ly:music?)
#{
  -\tweak ParenthesesItem #'stencils
#parentheses-item::calc-parenthesis-left-stencils
  -\parenthesize $arg
#})
parenthesizeRight = #(define-music-function (parser loc arg) (ly:music?)
#{
  -\tweak ParenthesesItem #'stencils
#parentheses-item::calc-parenthesis-right-stencils
  -\parenthesize $arg
#})


%%%%%%%%%%%%%


The \parenthesizeLeft and \parenthesizeRight work exactly like
\parenthesize, i.e.:

  e4.-\parenthesizeLeft->\> <e c>4.-\parenthesizeRight-> | % 3


HTH,
