[Caml-list] Quotation issue with camlp4 printer

The attached program prints out

    let x = """;;

when compiled with ocamlc and camlp4 version 3.12.0.  As you can see,
the string literal lacks an escape character.  I haven't tried version
3.12.1, but I didn't find anything about it in the release notes.  (To
reproduce:

    ocamlc.opt -c -I +camlp4 -pp camlp4orf -o quotation_bug.cmo quotation_bug.ml
    ocamlc.opt dynlink.cma -I +camlp4 camlp4lib.cma quotation_bug.cmo
-o quotation_bug.byte
    ./quotation_bug.byte
)

open Camlp4.PreCast
open Printf

let _loc = Loc.ghost

let () =
    let code = <:str_item< value x = "\"" >> in
    Printers.OCaml.print_implem code;
    print_string "\n"

The problem was also present in 3.12.1 and is now fixed in the SVN repository
in branch "version/3.12". Thanks for reporting the problem. Nevertheless I would
like to point out that you may also report it directly through the bugtracker (*).

Thanks for the quick fix.  I'll use the bugtracker in the future;
didn't notice the list-signature.
