I need a `git format-patch --attach-complete' for RT

I'm working with a system that doesn't play nice with git-format-patch / git-send-email. When you send mail to RT (e.g. http://rt.perl.org/) it'll always munge the original E-Mail, so inline patches won't work. Here's an example of this gone wrong:

        GitHub's mirror is now at mirrors/perl, not github/perl

The workaround is to:

    git format-patch --stdout origin.. > my-patches.patch
    *open your mail client*
    *attach patch as attachment*
    *send to RT*

It would be nicer if I could instead:

    git format-patch --attach-complete origin..
    git send-email *.patch

The --attach option doesn't work with RT because `git am' will take the commit message from the Subject/body of the message. RT messes with that.

Is there some existing workaround for this that I've missed?
