[PATCH 1/3] t/t5400-send-pack.sh: use the canonical test_expect_success syntax

[Ævar Arnfjörð Bjarmason]

Change t/t5400-send-pack.sh to use the usual test_expect_success
syntax, i.e. change:

    test_expect_success \
        'description'

To:

    test_expect_success 'description'

Like the rest of the tests in t/t5400-send-pack.sh do.

[PATCH 2/3] t/t5400-send-pack.sh: add test_when_finished commands

[Ævar Arnfjörð Bjarmason]

Change the tests in t/t5400-send-pack.sh to use test_when_finished to
unset git config variables that were set in the tests, e.g.:

    git config --unset $variable_they_set

This doesn't change the test behavior, but makes each test more
self-contained.

[PATCH 3/3] t/t5400-send-pack.sh: re-indent subshell invocation

[Ævar Arnfjörð Bjarmason]

Change a subshell invocation in t/t5400-send-pack.sh to use one line
per command in the subshell, that's the usual syntax we use for tests.

I agree that you are trying to do a good thing, but does this
implementation work in practice?  If somebody breaks send-pack in such a
way that this push succeeds, doesn't the &&-chain will prevent your
"when-finished" hook to be registered to begin with?  IOW, wouldn't you
want to have when-finished as _early_ as possible, before any test that
might fail to help us identify a new breakage?

The same comment applies to other two hunks in the patch.
