In Apple's Mail.App, can you reply with full headers?

For example, in Outlook (and most other mail software), replying will show you something like:

From: John Doe <>
Date: Monday, July 23, 2013 9:34 AM
To: Jane Doe <>
Cc: Bob <>
Subject: RE: Test Message simply says the following - which omits the import details of who was cc'd etc:

On Jul 23, 2012, at 9:34 AM, "John Doe" <> wrote:

I would much prefer over Outlook 2011, but I'm trapped without the ability to maintain the thread of recipients in replies.

Surely there's some way to change this?

Okay... I've got a workable solution:

Longtime users may remember the "ReplyWithHeaders" plugin that was abandoned years ago. Well, it's been resurrected and then abandoned again, but at the time of this writing works for OS X 10.8.4 and can be obtained here:

And if you've got a version of "ReplyWithHeaders" that doesn't work, it too can likely be be made to work simply by changing the UUID's per the instructions here:

From all my searching and testing, this appears to be the best solution available at this time.
