test: test_must_be_empty helper
There are quite a lot places where an output file is expected to be empty, and we fail the test when it is not. The output from running the test script with -i -v can be helped if we showed the unexpected contents at that point. We could of course do >expected.empty && test_cmp expected.empty actual but this is commmon enough to be done with a dedicated helper. Signed-off-by: Junio C Hamano <gitster@pobox.com>
