[issue11050] email.utils.getaddresses behavior contradicts RFC2822

[Ivan Egorov]

New submission from Ivan Egorov <egorich.3.04 at gmail.com>:

email.utils.getaddresses behaves wrong in following folding cases (outer single quote is not a part of value): 
'"A\r\n (B)" <c at d.org>'
'(A\r\n C) <d at e.org>'

The misbehavior occurs in at least 2.6, 2.7 and branches/py3k.

Both these strings are RFC 2822 compliant, but current getaddresses() implementation misbehaves on 'quoted-string' and 'comment' containing CRLF.

Following references the related RFC sections:
http://tools.ietf.org/html/rfc2822#section-3.4
http://tools.ietf.org/html/rfc2822#section-3.2.5

Attachment contains tests and patch for the case.
