NAME
	CloneTagItems -- copy a tag list. (V36)

   SYNOPSIS
	clone = CloneTagItems(original);
	D0		      A0

	struct TagItem *CloneTagItems(struct TagItem *);

   FUNCTION
	Copies the essential contents of a tag list into a new tag list.

	The cloning is such that calling FindTagItem() with a given tag on
	the original or cloned tag lists will always return the same
	tag value. That is, the ordering of the tags is maintained.

   INPUTS
	original - tag list to clone. May be NULL, in which case an
		   empty tag list is returned.

   RESULTS
	clone - copy of the original tag list, or NULL if there was not enough
		memory. This tag list must eventually by freed by calling
		FreeTagItems().
