Re: Time signature in French baroque music

Some time ago, I had asked how to define a compound time signature.  I got
some hints but couldn't quite obtain the right result.
For your question, the following snippet might be a start but you'll see
that something is missing from the incantation.

%---BEGIN--
\version "2.8.7"

#(define (single-number grob one)
  (let* ((layout (ly:grob-layout grob))
         (text (interpret-markup
                layout
                (ly:grob-alist-chain grob (ly:output-def-lookup layout 
'text-font-defaults))
                (markup (#:number one)))))
   text))

theMusic = \relative c'' {
  \time 3/4
  \override Staff.TimeSignature #'stencil =
  #(lambda (grob) (single-number grob "3"))
  a4 b g | f4 g2 |
}

\score {
    \theMusic
    \layout {}
}
%---END---

For my own problem, can someone help me out?  [I wonder why there
is still no easy way to create those time signatures.]
This is what I tried:

%---BEGIN---
#(define (compound-time-2 grob one two three four)
  (let* ((layout (ly:grob-layout grob))
         (text (interpret-markup
                layout
                (ly:grob-alist-chain grob (ly:output-def-lookup layout 
'text-font-defaults))
                (markup
                 #:line
                 (#:column (#:number one #:number two)
                  #:hspace -1 #:lower 0.5 "+"
                  #:column (#:number three #:number four))))))
   text))
%---END---

Thanks and best regards (and Happy New Year),
