This is a point of tension between the two reasons for knit: compression
and annotation.

On an XML file, annotations would be better served by an XML differ.
But I expect compression won't be significantly better, and having that
amount of storage format flux seems problematic.

I was only answering in terms of the user-facing diffing; "bzr diff" mainly.
