Maybe it is just me, but those last two lines would be much more
readable as:
if test "$eval_ret" = 0; then
eval_ret=$cleanup_ret
fi
assuming your "$test_ret" was supposed to be $eval_ret.

I don't know that we have necessarily have that principle. The most
important thing is that ugliness not escape to the test scripts
themselves, where we have to write many thousands of (hopefully
readable) lines.

This fix looks fine to me, and I tested it on FreeBSD 8.0. So:

I think Junio is much more carefree with changes that only touch test
infrastructure, as they cannot possibly be breaking git itself for
anybody.

To clarify my position, I am not that negative on the feature. I just
think it is a bit of a fool's errand, and I don't want to personally
spend any time on making it happen. If you think it is worth proceeding
and you can do so without breaking anything[1], I won't object.
[1] Yes, I am teasing you. But probably the complex part is now done,
and you and others can use test_when_finished() at will now, and we can
see if it actually makes anybody's life better.
