While updating the `history` function to use `argparse` I realized it is useful to define an option that can be used in three ways. First by using the short flag; e.g., `-n NNN`. Second by using the long flag; e.g., `--max NNN`. Third, as an implicit int flag; e.g., `-NNN`. This use case is now supported by a spec of the form `n#max`.
