As long as you do it on the python level, I'd think filtering the inventory
would be best thing. Ie. the bzrlib.export.export takes a tree as the first
argument. If you call it from a plugin directly, you can take the
RevisionTree, remove the entries you don't want from it's inventory (not sure
whether you have to copy it) and pass it to export.
