Fix bug in the folding of quoted strings when flattening an email message
using a modern email policy. Previously when a quoted string was folded so
that it spanned more than one line, the surrounding quotes and internal
escapes would be omitted. This could theoretically be used to spoof header
lines using a carefully constructed quoted string if the resulting rendered
email was transmitted or re-parsed.

.. section: Security
Fix a potential denial of service in the :mod:`imaplib` module. When
connecting to a malicious server, it could cause an arbitrary amount of
memory to be allocated. On many systems this is harmless as unused virtual
memory is only a mapping, but if this hit a virtual address size limit it
could lead to a :exc:`MemoryError` or other process crash. On unusual
systems or builds where all allocated memory is touched and backed by actual
ram or storage it could've consumed resources doing so until similarly
crashing.
