While the adjustment is small, it would be better to avoid the ifdef in all programs. I think there is a -Zwildcard option to auto enable for all programs? Also is there an option to disable this expansion at runtime (which should be documented if available). For example to allow deleting a file called '*', which seems like a more likely occurrence on this platform. thanks, Pádraig.
