Wow, bash is very slow at this:

address@hidden tmp]$ time dash ./s.sh `seq 1 1000`

real    0m1.034s
user    0m0.844s
sys     0m0.007s
address@hidden tmp]$ time bash ./s.sh `seq 1 1000`

real    0m16.833s
user    0m13.703s
sys     0m0.050s
address@hidden tmp]$ time zsh ./s.sh `seq 1 1000`

real    0m0.984s
user    0m0.743s
sys     0m0.065s
address@hidden tmp]$ cat s.sh
     for lt_wr_arg
     do
       case $lt_wr_arg in
       --lt-*) ;;
       *) set x "$@" "$lt_wr_arg" ;;
       esac
       shift
     done
