* libguile/vectors.c (scm_vector): Use SCM_I_VECTOR_WELTS on new vector instead of generic scm_vector_elements; cf. scm_vector_copy(). (scm_vector_elements): Forward to scm_vector_writable_elements(). (scm_vector_writable_elements): Remove special error message for weak vector arg. * libguile/generalized-vectors.c (SCM_VALIDATE_VECTOR_WITH_HANDLE): Remove unused macro. * libguile/array-handle.c (scm_array_handle_elements): Forward to scm_array_handle_writable_elements().
