It seems more natural, especially in the presence of sparse arrays, to
allow references to unset array elements in arithmetic contexts not to
abort the shell if nounset is enabled. ksh93 and mksh behave the same
way, even as they also treat references to unset array elements as fatal
errors when nounset is set.
