Whoops. Didn't notice the section number, my apologies.

Above is obviously for printf(3). For printf(1) it indeed says:
9. The format operand shall be reused as often as necessary to
satisfy the argument operands. Any extra c or s conversion
specifiers shall be evaluated as if a null string argument were
supplied; other extra conversion specifications shall be evaluated
as if a zero argument were supplied. If the format operand
contains no conversion specifications and argument operands are
present, the results are unspecified.
