The SUSv3 has `none' in the OPTIONS section of the printf description.
The description of that value in the `Utility Description Defaults'
section of the standard requires that commands which accept operands
but not options to recognize `--' and handle it appropriately.

The format string is an operand and is described as such.

The coreutils implementation is not compliant.
