adduser "send message to new user" prompts

[Glen Anderson]

When being asked for additional recipients the option list of "no
carbon copy root second_mail_address" is confusing so rephrase the
question and use a blank list. It also makes more sense to first ask
the user if they want to send mail before asking about the specifics
of the message.
