I thought about that and decided to not suggest it.  I don't like
conflating something
that is, in essence, a configurable setting with real operands.  I'd
prefer to suggest
"-g" to our BSD friends.  :)

Were it to be implemented in GNU's fmt, you would have to pass two tests:

1. does it match a file name?  If not,
2. is the first (or second) operand a number? (decimal only, or hex/octal, too?)
