If you can wait for 3.05, or if you are willing to use the CVS
version, you'll be able to write:

  let sprint fmt =
    let do_output s = print_endline ("BEGIN: " ^ s); "" in
    Printf.kprintf do_output fmt
  ;;

The tail-call to kprintf allows it to get the extra arguments thanks
to currying.  The do_output function must return a string (which is
returned by sprint) for technical reasons.  (This may change before
the release.)
