I wanted to write a little callback to remove all occurrencies

\version "2.19.63"
music = {
c'4-3 d'-0 e'-2 f'-3 | g'1-0
}
\score {
\new Staff \with {
\override Fingering.stencil =
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#(lambda (grob)
[...]
(ly:grob-property grob 'stencil))))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Compiling this nearly MWE, I get:
Warning: Fingering has empty extent and non-empty stencil.
Warning: Fingering has empty extent and non-empty stencil.
And *no* fingering at all is shown in the resulting score.
What am I doing wrong?
Recursion: see Recursion.
Ah, yes!
I think I intermingled the idea to use Fingering.after-line-breaking
(where stencil is already defined) and Fingering.stencil (to remove the
stencil before any layout decisions are completed).
Thanks for clarification!
