This sounds useful… but I don't quite know what you are suggesting I do. Do you 
mean this (which appears to work, but still uses ly:make-stencil):

#(define-markup-command (when-property layout props symbol markp) (symbol? 
markup?)
  (if (chain-assoc-get symbol props)
      (interpret-markup layout props markp)
      (ly:make-stencil empty-stencil)))

?

I tried a lot of things without ly:make-stencil, and they all failed.

Thanks,
Kieren.
