Ah, good catch, I hadn't considered that interpretation, and that is a
much more relevant topic.
I wouldn't WANT to see "remove all references", though; doing that in
an automated way is sure to cause problems. "Find all references" on
the other hand IS a good approach to at least get started at it.
