39758: revise 39704 for array and hash parameters; more POSIXBUITINS tweaks for
export 39704 was commit 0f5e670, forgot to reference article number in that log. "typeset -p" outputs "typeset" for array and hash parameters, even when exported, because those types can be marked export but are never pushed to the enviroment. For POSIXBUILTINS, "export var" does not implicitly set $var, and its export state is preserved when assigned (but not when explicitly unset).
