If this is ``None``, the prompt will not be changed. This will be formatted with the new and continuation prompts as positional parameters, so you can use ``{}`` style formatting to insert them into the command. :param str new_prompt: The more unique prompt to expect after the change. :param str extra_init_cmd: Commands to do extra initialisation, such as disabling pagers.
