...then use it here again. But you don't expect any output since you
already updated. As you already know you can't pass "None" to
run_and_verify_update(). Instead, redefine expected_out to expect
nothing:
expected_output = wc.State(wc_backup, {})
The odd error you were getting is due to tree.build_tree_from_checkout()
in actions.run_and_verify_update(). It tries to build a tree out of the
non-existant output from the update and compare it to the
expected_output tree you passed in. Yes, the error message is less than
worthless, but nobody has gotten around to fixing it yet.
