* t/ax/is_newest: Rewrite to be Bourne-compatible, for /bin/sh shells like Solaris' that are not POSIX-conforming. The script is so small that such a rewrite is easier than going through the hoops that would be required to ensure this script is always executed with a POSIX shell. * t/ax/is: Add a comment stating that this script is to be kept Bourne compatible as well.
