Further Googling gives http://lsr.dsi.unimi.it/LSR/Snippet?id=616 :
%<-------------------------------------------

stringNumberSpanner =
#(define-music-function (parser location StringNumber) (string?)
  #{
    \override TextSpanner #'style = #'solid
    \override TextSpanner #'font-size = #-5
    \override TextSpanner #'(bound-details left stencil-align-dir-y) = #CENTER
    \override TextSpanner #'(bound-details left text) = \markup { \circle 
\number $StringNumber }
  #})


\relative c {
  \clef "treble_8"
  \stringNumberSpanner "5"
  \textSpannerDown
  a8\startTextSpan
  b c d e f\stopTextSpan
  \stringNumberSpanner "4"
  g\startTextSpan a
  bes4 a g2\stopTextSpan
}

%<-------------------------------------------

which is closer in appearance, but I haven't the Scheme fu to modify the 
stringNumberSpanner function to incorporate the startTextSpan and number 
of notes. Ideally, one would wind up with something like a8\fSpan {"5" 
4} which would extend a line for 4 of the note value of the starting note.

Maybe I'll have a chance to RTFM about Extending, but for the moment, 
desperately in need of practice as I am, the analog pencil will have to 
suffice!

Cheers,
Colin
