Bug description

The Format module in latest trunk prints <b 4> into the output.
This breaks the build of OCamlnet for example (its rpc-generator prints a verbatim
<b 4> into the output).

Steps to reproduce

$ opam switch 4.02.0dev+trunk
$ eval opam config env
$ ocaml
OCaml version 4.03.0+dev0-2014-05-12

Format.printf "@[<b 4>@]@.";;

<b 4>

• : unit = ()

$ opam switch system
$ eval opam config env

    OCaml version 4.01.0

Format.printf "@[<b 4>@]@.";;

• : unit = ()
