email._parseaddr AddrlistClass incorrectly parse multilined comment (display name).

According to RFC2822, folding white space is allowed in display name. Thus following header should be parsed as a single address "foo@example.com" having multilined display name.

To: Foo
Bar <foo@example.com>

On the other hand, following program results in:
from email.Utils import getaddresses
s = """Foo
Bar <foo@example.com>
"""
print getaddresses([s])

[('', 'Foo'), ('Bar', 'foo@example.com')]

Note that the first address is not valid one.

Looks like the bug is in _parseaddr.py. Please check the patch.
