Don't ask me how it is done, but at least that's how it works in lilypond:

lilypond -e '(display (string->list (format "abc~sdef" "ffff")))'

prints 

(a b c " f f f f " d e f)

So, apparently, format simply returned the string properly formatted. (Of 
course, I had tried out my sample code before posting it on the mailing list, 
in particular since I'm absolutely new to scheme).

Cheers,
Reinhold
