Let's see if the line breaks survive.
It basically removes the bogus (format[inpos + 1] != '%' will always be
true there) arg number check and moves the right one outside the special
case for "complicated" format specifiers.

Description:
------------
printf('%s - %s %s %3$s %2$s', 1, 2, 3);
complains:
Warning: printf(): Too few arguments in /home/bertheau/printf.php on
line 2
printf('%s - %s %s %3$s %2$s', 1, 2, 3, 4);
does not complain and prints:
1 - 2 3 3 2
I expect the first version to not complain and print what the second
version prints.
