    Research direction

    Start by comparing the supplied utf8-header-failure.mail input with mf.9__mi0bf.out, then read email_flatten.py to trace how BytesGenerator.flatten changes the headers. Use the existing email tests as the place to add coverage, and consider the issue done when the reproduced header indentation is preserved in the generated message.
