I personally think that --format=raw *should* work on non-leaf parts; i
don't know if that was the original intent.

I hope the tests for this feature can eventually include some weird
compound parts with whitespace-wrapped header lines, odd MIME
delimiters, character encodings, etc.  It would be really good if the
--part=whatever --format=raw output produces byte-for-byte identical
streams.  Both PGP/MIME and S/MIME signatures rely on explicit opacity
of the signed MIME parts, so being able to retrieve the signed data
precisely would be quite useful for weird corner cases.
