* generic/tclBasic.c: For compatibility with earlier Tcl releases,

        * generic/tclResult.c:  when a command procedure simply does a
        * generic/tclTest.c:    "return TCL_RETURN;" we must interpret that
        * tests/result.test:    the same as
        "return Tcl_SetReturnOptions(interp, Tcl_NewObj());"  [Bug 1209759].
