 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).
