I think they mean use "--wrap=0" instead of "-w0" as it's a little better self-documenting for those who come across your script.

In general I always try to use the long-form options in scripts as readability is more important that conciseness.

The article notes this was not possible in their specific context, as only the short form is implemented in busybox.

That's what I meant indeed. The article never mentions busybox in the text, does it?
