But you have to save the attached .patch files and then run git am on
those.  Typically, without attachments, you'd run `git am` on the
message (mbox) directly.  Each mail is a patch in that sense, and a
separate cover letter is sent first when there's some introductory words
that need to be said.

Yes, but users would have to apply the customization to get the Emacs
way of working, I think.
