Bug report

When during address list folding a separating comma ends up on a folded line containing that is to be unicode-encoded than the separator itself is also unicode encoded. Instead the comma should still a plain comma.

This is rejected by some mail servers:

ZZZ: host YYY said:
    550 Invalid address in message header. Consult RFC2822. (in reply to end of
    DATA command)

Minimal example:

>>> import email
>>> m = email.message.EmailMessage()
>>> t = '01234567890123456789012345678901234567890123456789012345678901@example.org, ä <foo@example.org>'
>>> m['to'] = t
>>> m.as_string()
'to: 01234567890123456789012345678901234567890123456789012345678901@example.org\n =?utf-8?q?=2C?= =?utf-8?q?=C3=A4?= <foo@example.org>\n\n'

pythonGH-100884: email/_header_value_parser: use existing ListSeparator

There already is already a predefined object with the correct
properties, use it.

ListSeparator should not be encoded. This could happen when a long line
pushes its separator to the next line, which would have been encoded.

Fixes python#100884
