Long Method should count nested assignments

[kevinrutherford]

The following code includes 3 nested assignments, yet none of these contribute to the method's "length":

def parse(arg, argv, &error)
  if !(val = arg) and (argv.empty? or /\A-/ =~ (val = argv[0]))
    return nil, block, nil
  end
  opt = (val = parse_arg(val, &error))[1]
  val = conv_arg(*val)
  if opt and !arg
    argv.shift
  else
    val[0] = nil
  end
  val
end

The metho'ds length is reported as 6, but should be 9.
