This is how bash behaves:
The format is reused as necessary to consume all of the argu-
ments. If the format requires more arguments than are supplied,
the extra format specifications behave as if a zero value or
null string, as appropriate, had been supplied.
This is how Posix specifies printf to work. I know it doesn't have %q,
but bash doesn't really differentiate between %q and %s.
