ngx_conf_set_str_array_slot() bug?

[Paulo Silva]

Hi,
For a module with the following configuration

/**
 * do_nothing_tuple "val1" "val2";
 */
static ngx_command_t  ngx_http_do_nothing_commands[] = {

    {
        ngx_string("do_nothing_tuple"),
        NGX_HTTP_LOC_CONF | NGX_CONF_TAKE2,
        ngx_conf_set_str_array_slot,
        NGX_HTTP_LOC_CONF_OFFSET,
        offsetof(ngx_http_do_nothing_loc_conf_t, tuple),
        NULL
    },

    ngx_null_command
};

I was expecting that ngx_conf_set_str_array_slot() would create and
initialize an ngx_array_t with two elements (nelts ==  2), the given
parameters, but it saves just the first element (see
http://fossies.org/dox/nginx-1.7.4/ngx__conf__file_8c_source.html#l01034).

Is it a bug or ngx_conf_set_str_array_slot() use case is different?
