> Do you think the summary object should provide a single `formatted_colorized_rerun_commands` method that returns the full string with line breaks and the `"Failed examples:"` bit? That would make it easier for custom formatters that don't inherit to produce the same output.

My thinking was I didn't want I to restrict this output, people might want to call this something different (e.g. "Examples to re-run:") or something, but also that they might want to use this progamatically (e.g. dump into a csv file, or a json file etc) which makes an array preferable.

I could go for two methods?
