60 (* This module is used by unparse_c, but because unparse_c have also
61 * the list of tokens, pretty_print_c could be useless in the future
62 * (except that the ast_c have some fake tokens not present in the list
63 * of tokens so it's still useful). But this module is also useful to
64 * unparse C when you don't have the ordered list of tokens separately,
65 * or tokens without position information, for instance when you want
66 * to pretty print some piece of C that was generated, or some
67 * abstract-lined piece of code, etc. *)
