Following up to myself, here's what I decided to do for now:
out = StringIO()
generator = Generator(out, False, 0) # disable reformatting measures
generator.flatten(message)
return out.getvalue()
Problems may apparently remain with superfluous whitespace found around header
keys in any parsed messages, but the above seems to prevent the blatant
rewriting I experienced with the Message.as_string method, doing so by
overriding the Generator defaults.
