mktag tests: stress test whitespace handling
Add tests for a couple of whitespace edge cases around the header/body boundary. I consider the requirement for a blank line before the empty body a bug, it's a long-standing regression which goes against the command's documented behavior. This bug will be addressed in a follow-up change. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
