So just to get this clear for myself, "bzr split tests" would accomplish
part of the job - turning the tests tree into a separate branch in place,
at which point you could arrange to push up the original tree, without
the now independent tests tree, BUT... history is preserved for the
original
tree, so a recipient could still reconstruct past versions of the private
files that were in tests before the split.  Is that right?
