When splitting up tests like:
git init xyz &&
[do with xyz]
Let's do:
# test 1
test_when_finished "rm -rf xyz" &&
git init xyz &&
[do with xyz]
# test 2
test_when_finished "rm -rf xyz" &&
git init xyz &&
[do with xyz]
Instead of, as here:
# test 1
git init xyz &&
[do with xyz]
# test 2
rm -rf xyz &&
git init xyz &&
[do with xyz]
This isn't a logic error, but just a better idiom. Better to have the
thing creating stuff clean it up, than other tests being aware of their
order and (possibly redundantly, if we skip tests), clean up after
earlier tests.
