Personnaly I wouldn't use the 'minus' command as it is to indicate a
'portamento'.
See:
minus =
#(define-music-function (parser location fingering) (ly:music?)
(let ((music (make-music 'FingeringEvent))
(finger (ly:music-property fingering 'digit)))
(set! (ly:music-property music 'tweaks)
(acons 'stencil
(lambda (grob)
(grob-interpret-markup grob
(make-concat-markup
(list
(markup #:line
(#:translate
(cons 0.1 0.5)
(#:override
(cons (quote
thickness) 2.2)
(#:draw-line (cons
0.6 0)))))
(number->string finger)))))
(ly:music-property music 'tweaks)))
music))
port =
#(define-music-function (parser location fingering) (ly:music?)
(let ((music (make-music 'FingeringEvent))
(finger (ly:music-property fingering 'digit)))
(set! (ly:music-property music 'tweaks)

music))
{
