I don't at all mind this solution to the problem, if it works for that's cool.

But FWIW something you may have missed is that you can just use
prove(1) for this, which is why I initially patched git.git to support
TAP, so I didn't have to implement stuff like this.

Heh. I think each iteration of this patch will be destined to have
somebody[1] point Johannes at prove. ;)

(But I really do recommend prove if you can use it).
