    The function of your tool is to invoke get_maintainer and put the
    addresses from there everywhere appropriate including, in particular,
    the CCs of the cover letter.
    The only reason your tool is needed is because there is no other tool
    that gets the cover letter right.
    But I often have a set of patches where I have manually decided who
    they should be CCd to, and put appropriate tags in my commit
    messages.  I don't blindly use get_maintainer.
    When I do this, there is nothing that gets the CC for the cover letter
    right.  (I sometimes bodge it.)  Your tool already knows how to
    extract CCs from the individual non-cover-letter patches and add them
    to the cover letter.  That is the function I want - to do that, but
    not run get_maintainer.

That makes sense and can be easily done via an option: e.g.
--insert cover|-i cover or a separate option. Let me know whether
you have a preference regarding naming/options.
    Nor do I need, I think, your tool to edit any of the non-cover-letter
    patches, since git-send-email will find CCs in their bodies and use
    them for the email recipients.
    I don't think I really mind where the CCs end up in the cover letter
    (whether they are in the body, or just in the email header), but
    others have made a convincing argument that they should be in the
    body, so that is fine.
    Does that make sense ?
