[PATCH] send-email: use sanitized address for cc

[changbin . du]

From: "Du, Changbin" <changbin...@gmail.com>

Some username in the email address may include a ','. In this case,
we need quoting the username field so it will not be parsed as two
single addresses by Mail::Address->parse().

For example, my eamil address "Du, Changbin <changbin...@gmail.com>"
can be parsed as two addresses "Du" and "Changbin <changbin...@gmail.com>"
if username is not quoted. ("Du, Changbin" is a legal format of signature
in Chinese)

The sanitized address can be used because quote is added automactically.

Signed-off-by: Du, Changbin <changbin...@gmail.com>
