Yes, "length modifiers" are not allowed for awk's printf operator
and it's safer to disallow them explicitly.
Quick check: between % sign and [diouxXfeEgGcs] character (on the right side)
only the following chars are allowed: [-+0-9 #].

%l should be disabled because there is no such "conversion
specifiers". %lld - too because "length modifiers" are
not allowed for awk's printf (see above).
