This isn't acceptable to me in its current form.

The most likely use case for this is to add
"CC: <foo>" entries to a commit description.

I doubt anyone cares about the cc'd mailing lists
in a commit description.

I'd prefer that commit descriptions don't have
"CC:" lines at all as it was really only useful
for adding email address to a proposed patch and
as commit information is actually pretty useless.

There are now simple ways to make sure a patch
submission is cc'd to appropriate parties.

git send-email supports --cc-cmd

I do not believe that's true.

I want to proposed patches to moderated lists
and believe everyone really should too.

I don't care if moderated lists send a
"waiting for moderation" message as long as the
list gets the proposed patch eventually.

I think only Peter cares about those, to him,
superfluous "being moderated" messages.

I'd prefer the user specify the prefix.

I do not care for this.

If a switch is specified on the command line,
it should be followed.

infront isn't a word.

It should not be $cc_prefix either, but $output_prefix

And this should become something like:

if (!$saw($address)) {
my $output_address = "";
$output_address .= "$output_prefix " if (defined $output_prefix);
$output_address .= $address;
$output_address .= " ($role)" if ($output_roles);
push(@lines, $output_address);
$saw{$address} = 1;
}
