- will be an gr_expect_prompt(). Exception: resume does not
- wait for the prompt, because the terminal is being handed over
- to the inferior. However, the next thing which happens after that
- is a bug_wait which does wait for the prompt.
- Note that this includes abnormal exit, e.g. error(). This is
- necessary to prevent getting into states from which we can't
- recover. */
