Re: [PATCH 1/2] t3400: make test clean up after itself

> This test intentionally creates a file which causes rebase to fail, thus
> it is important that this file be deleted before subsequent tests are
> run which are not expecting such a failure. In the past, the common way

> tests. With the introduction of 'test_when_finished', however, tests can
> be responsible for their own cleanup. Therefore, update this test to
