Looks like the definition [earlier in the code] is

                    (all-stils
                      (map
                        (lambda (mrkp)
                          (if (null? mrkp)
                              empty-stencil
                              (grob-interpret-markup grob
                                (if (markup-list? mrkp)
                                    (make-concat-markup mrkp)
                                    mrkp))))
                          stil-candidates))

In case that helps…?

Thanks,
