- Numeric arguments are to be in the form "num1, num2" where the
- separator may be either a space, comma or both. If only one
- argument is given, both will be assumed to be the same. If no
- arguments are given, defaults vary from command to command. For
- example, "delete" and "keep" both default to be the current line
- only. Special cases are made for the letters 't', 'b' and 'r' as
- well as the period, refering to the top, bottom, remembered (see
- <z> key, page 4) and current line, respectively.
