I think the logic is wrong.  Even when you have configured to usually ask,
you may want to say "I know Cc settings for this particular series is all
good, but I still want the safety in my future invocations.".

How about doing it this way instead?

This is not "Set confirm" but "set the default value to $confirm".  Also
set $confirm_unconfigured = "true" here.

And use it here; give some help for people who haven't seen this new
message and haven't decided:

	    if (!$confirm_unconfigured) {
		print "By default the command asks if you are sure about\n";
		print "the CC list computed from various places.  If you\n";
                print "do not want this confirmation step, you can say\n";
                print "    $ git config --global sendemail.confirm never\n";
                print "to squelch it.\n";
		print "A good setting might be:\n";
                print "    $ git config --global sendemail.confirm auto\n";
		print "to squelch this help text that is given until you\n";
		print "configure the variable to some value.\n";
	    }
