Agreed. V8 will switch to 0 for failure and 1 for success for the TEST,
TEST_TODO, and check macros.

My hope is that test-lib.c will not have to grow too extensively after
this series; that said, it's already been a pain to have to adjust the
t0080 expected text several times just during development of this
series. I'll look into splitting this into several "meta-tests", but I'm
not sure I'll get to it for V8 yet.

Sounds good to me.
