    # Well... that isn't strictly true. The contents of the files
    # might not be UTF-8, so the "diff" portion will be hosed.
    #
    # If you want a truly "proper" commit message, then you'd use
    # multipart MIME messages, with each file going into its own part,
    # and labeled with an appropriate MIME type and charset. Of
    # course, we haven't defined a charset property yet, but no biggy.
    #
    # Going with multipart will surely throw out the notion of "cut
    # out the patch from the email and apply." But then again: the
    # commit emailer could see that all portions are in the same
    # charset and skip the multipart thang.
    #
    # etc etc

    # Basically: adding/tweaking the content-type is nice, but don't
    # think that is the proper solution.
