Augment the docs to clarify that msg:append_header and msg:prepend_header do no modification of the value by default. Adjust the wrapping used by Header:new_unstructured so that it hard wraps before the SMTP line length limit. Add optional encode parameter to msg:append_header and msg:prepend_header so that those methods can opt-in to the Header:new_unstructured formatting. Add HeaderMap:append method to mirror the existing HeaderMap:prepend method. Add unit tests that demonstrate the effect of wrapping/encoding for both the "dumb" msg:append_header and msg:prepend_header functions, and the "smarter" HeaderMap:prepend and HeaderMap:append methods that always encode their parameters. Update the docs for the headermap flavor of these methods to indicate that they will always encode the value.
