That's due to how make-line-stencil works.
Why not more generic (extending the built-in \underline):
#(define-markup-command (underline-h layout props arg)
(markup?)
#:category font
#:properties ((thickness 1) (offset 2) (gap 2) (amount 1))
(let* ((thick (ly:output-def-lookup layout 'line-thickness))
(underline-thick (* thickness thick))
(m (interpret-markup layout props arg))
(stil-x-ext (ly:stencil-extent m X))
(x1 (car stil-x-ext))
(x2 (cdr stil-x-ext))
(y (* thick (- offset)))
(y-off (* thick (- gap)))
(lines
(map
(lambda (i)
(let ((y-dist (+ y (* i y-off))))
(make-line-stencil underline-thick x1 y-dist x2 y-dist)))
(iota amount 0 1))))
(apply ly:stencil-add m lines)))
\markup
\underline-h "underlined"
\markup
\override #'(amount . 2)
\underline-h "underlined"
\markup
\override #'(amount . 3)
\underline-h "underlined"
\markup
\override #'(offset . 4)
\override #'(amount . 3)
\underline-h "underlined"
\markup
\override #'(offset . 4)
\override #'(amount . 3)
\override #'(gap . 3)
\underline-h "underlined"
Cheers,
Harm
