If we fail to cd to 'repo', "$(cd repo && pwd)/../repolink/a" would
silently expand to nonsense, but presumably "test-tool -C repo"
would fail loudly in such a case, so we should be OK here?

I am not sure if the above with full of "git -C" is strictly an
improvement over
(
cd b &&
echo false >expect &&
git config --bool core.bare >actual &&
test_cmp expect actual &&
git fetch
)
and even if it were, the reason why it is better would be vastly
different from the reason why it is better that we no longer do
"test $(cmd) = false". I very much hate the pattern described on
the commit title of this step (which by definition this patch fixes
many instances of). I.e.
(cd ...; test <op> $(git ...))
might be something you find that needs improvements, but "don't lose
exit status" ONLY applies to the "test <op> $(git ...)" part, and
the other half, i.e. (cd ...), has nothing to do with "don't lose
exit status" badness.
