    Message : tests: fix automatic re-execution of tests with Zsh * defs: Use '$argv0' instead of '$0'. With Zsh not started right away in Bourne-compatibility mode, the latter will be the path not of the test script itself, but of the file it's currently sourcing -- i.e., in our case, './defs'. This would cause the automatic re-execution code to execute './defs' (basically a no-op) rather than re-run the test correctly. Signed-off-by: Stefano Lattarini <stefano.lattarini@gmail.com>
