This can display one prompt at the first line, and a continuation prompt (e.g, just dots) on all the following lines. This `PromptMargin` implementation has been largely superseded in favor of the `get_line_prefix` attribute of `Window`. The reason is that a margin is always a fixed width, while `get_line_prefix` can return a variable width prefix in front of every line, making it more powerful, especially for line continuations. :param get_prompt: Callable returns formatted text or a list of `(style_str, type)` tuples to be shown as the prompt at the first line. :param get_continuation: Callable that takes three inputs. The width (int), line_number (int), and is_soft_wrap (bool). It should return formatted text or a list of `(style_str, type)` tuples for the next lines of the input.
