This bit I don't understand. (#:column (one num)) would be the equivalent of

\markup \center-column { one num }, right? How would I do \markup

\center-column {\line {one + two + three} num }?

See Notation Reference 6.4.1 Markup construction in Scheme

(markup #:center-column ((#:line (one two three)) num))

4) decide if you want to keep the #:vcenter command

Probably not. I'm guessing.

5) somehow incorporate your new argument (three) in with the rest

   of the arguments.

This bit confuses me. Isn't it incorporated by adding "three" everywhere?

Yep, you seem to have it right.

Okay, now I have 

#(define ((compound-time one two three num) grob)

  (grob-interpret-markup grob

    (markup #:override '(baseline-skip . 0) #:number

    (markup #:center-column ((#:line (one "+" two "+" three)) num))

      )))

Which looks like just a really complicated way of doing 

         \override Staff.TimeSignature #'stencil = #ly:text-interface::print

         \override Staff.TimeSignature #'text = \markup {

            \center-column {

               \line { \musicglyph #"three" \musicglyph #"plus" \musicglyph #"three" \musicglyph #"plus" \musicglyph #"two" }

               \line { \musicglyph #"eight" }

            }

(my initial attempt)

 

Neither of which moves the Time signature to adjust for the wider space of "3+3+2". So, is there a better way of achieving this?
