The default setting of IFS is "<space><tab><newline>", which I show
typed out because none of those are printable. Changing it to a space
only would only be needed if something had already previously changed
it to something else. I believe suggesting to people that they should
set it to a space out of context will be confusing.
You would only need to change it to a space if previously you had set
IFS to something else that did not contain a space. If they did not
do that previously then they do not need to do this here. The problem
must be something else. In this case I think it is confusion about
walking through a list of items.
