When an option is changed on a command object, calling ensure_finalized for a second time will not run finalize_options again, because ensure_finalized is a no-op the second time. By resetting the finalized attribute, we can be sure that whatever computation takes place in finalize_options will happen again. (In test_command_clean, I removed two lines that were a no-op.)
