The Cc list above has been expanded by additional
addresses found in the patch commit message. By default
send-email prompts before sending whenever this occurs.
This behavior is controlled by the sendemail.confirm
configuration setting.
​
For additional information, run 'git send-email --help'.
To retain the current behavior, but squelch this message,
run 'git config --global sendemail.confirm auto'.
