Return the entire message flatten as a string. When optional
\var{unixfrom} is \code{True}, the envelope header is included in the
returned string. \var{unixfrom} defaults to \code{False}.

+Note that this method is provided as a convenience and may not always
+format the message the way you want. For more flexibility,
+instantiate a \class{Generator} instance and use its
+\method{flatten()} method directly. For example:

+fp = StringIO()
+g = Generator(mangle_from_=False, maxheaderlen=60)
+g.flatten(msg)
