I do need information about the file content differences too though. I
just tried this and it didn't tell me anything about the lines that were
different between the two trees.

What I need is something I can grab a count of lines added/removed in
the diff of two trees on a file by file basis.

I'll continue to dig around bzrlib and see if I find anything useful. It
seems to me that what would be required is an object like DiffTree that
provides an abstract representation of the diff, but I can't see
anything like that.
