Subject: [Caml-list] A question about Format boxes

The example at
<URL:http://caml.inria.fr/resources/doc/guides/format.en.html#hov-boxes>
shows a major difference in the output of packing versus structural hov
boxes.  However, in my experiments I cannot achieve the output this
example assigns to "packing" boxes.  (OCaml 3.12)

My examples from the REPL are below.  Would someone be able to tell me
what I am doing incorrectly?

# Format.printf "@[<hv 2>(---@\n@[<hv 2>(---@\n@[<hv 2>(---@,)@]@,)@]@,)@]@\n";;
(---
  (---
    (---)))
- : unit = ()
# Format.printf "@[<hov 2>(---@\n@[<hov 2>(---@\n@[<hov 2>(---@,)@]@,)@]@,)@]@\n";;
(---
  (---
    (---)))
- : unit = ()
# Format.printf "@[<2>(---@\n@[<2>(---@\n@[<2>(---@,)@]@,)@]@,)@]@\n";;
(---
  (---
    (---)))
- : unit = ()
# Format.printf "@[<b 2>(---@\n@[<b 2>(---@\n@[<b 2>(---@,)@]@,)@]@,)@]@\n";;
(---
  (---
    (---)))
- : unit = ()
