While doing delayed expansion of escape sequences in macro arguments,
correctly check for failure of the in-place expansion function. If an argument not only does recursive delayed expansion but infinitely recursive delayed expansion, this bug could result in an ESCAPE_EXPAND assertion failure. Thanks to Eric van Gyzen <vangyzen at FreeBSD> for finding this bug by inspecting FreeBSD source code.
