Hi Andrew,

you post your request on the user-list, thus I assume you don't ask
for extending the source code but for a custom solution.

In 2.18.2 you can do

omitAcc =
  #(define-music-function (parser location music) (ly:music?)
     #{ \tweak Accidental.stencil ##f $music #})

Thanks David Kastrup 2.19.24 allows for:

omitAcc = \tweak Accidental.stencil ##f \etc
{ < \omitAcc cis' ces'' > }


Cheers,
  Harm
