_split_header(): Split on folding whitespace if the attempt to split
on semi-colons failed.
_split_header(): Patch by Matthew Cowles for fixing SF bug # 471918,
Generator splitting long headers.
failobj, and when getting the subtype use 'plain' as the failobj.
text/plain is supposed to be the default if the message contains no
Content-Type: header.
headers. It does not parse the body of the message, instead simply
assigning it as a string to the container's payload. This can be much
faster when you're only interested in a message's header.
Also, add a clause to the big-if to handle message/delivery-status
content types. These create a message with subparts that are
Message instances, which best represent the header blocks of this
content type.
get_type(): Use a compiled regular expression, which can be shared.
_get_params_preserve(): A helper method which extracts the header's
parameter list preserving value quoting. I'm not sure that this
needs to be a public method. It's necessary because we want
get_param() and friends to return the unquoted parameter value,
however we want the quote-preserved form for set_boundary().
get_params(), get_param(), set_boundary(): Implement in terms of
_get_params_preserve().
walk(): Yield ourself first, then recurse over our subparts (if any).
Text.py and class Text => MIMEText.py and MIMEText
MessageRFC822.py and class MessageRFC822 => MIMEMessage.py and MIMEMessage
These are renamed so as to be more consistent; these are MIME specific
derived classes for when creating the object model out of whole cloth.
_handle_text(): If the payload is None, then just return (i.e. don't
write anything). Subparts of message/delivery-status types
will have this property since they are just blocks of headers.
Also, when raising the TypeError, include the type of the
payload in the error message.
_handle_multipart(), _handle_message(): When creating a clone of self,
pass in our _mangle_from_ and maxheaderlen flags so the clone
has the same behavior.
_handle_message_delivery_status(): New method to do the proper
printing of message/delivery-status type messages. These have
to be handled differently than other message/* types because
their payloads are subparts containing just blocks of headers.
In class DecodedGenerator:
_dispatch(): Skip over multipart/* messages since we don't care
about them, and don't want the non-text format to appear in
the printed results.

mimelib and email, but most of the implementations are shared (except
where cool Py2.2 stuff like generators are used).
