More than half of Bazaar codebase is actually tests and benchmarks.
You need to exclude bzrlib/tests and bzrlib/benchmarks to get info about actual code.

Also Bazaar supports more concepts, more features/workflows and tows support
for numerous old repo formats. I think this explains its codebase size.
