@majorheading Description

Run a test using the awk program found on AWK variable. The test being
run has TEST-BODY as body and is feeded with TEST-INPUT. Check if the
test gives the expected output. If successful execute ACTION-IF-SUCCESS
otherwise ACTION-IF-FAILURE.

This work is heavily based upon testawk.sh script by Heiner Steven. You
should find his script (and related works) at
<http://www.shelldorado.com/articles/awkcompat.html>. Thanks to
Alessandro Massignan for his suggestions and extensive nawk tests on
FreeBSD.
