| * awk: fix corner case in awk_printfDenys Vlasenko2021-07-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | Example where it wasn't working: awk 'BEGIN { printf "qwe %s rty %c uio\n", "a", 0, "c" }' - the NUL printing in %c caused premature stop of printing. function old new delta awk_printf 593 596 +3 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
