What does a diff on two doctrees get you that a diff on the source
files wouldn't? Presumably the two docs are related (one is derivative
of the other, or both derive from a common ancestor doc), otherwise a
diff would be useless. I'd just use the standard "diff" tool, possibly
normalizing first. Is a tree-diff tool worth all this extra effort?
