To email a patch you can use a shell command like 'git format-patch -1'
to create a file, and then attach the file to your email. This nicely

agents. To send just one such patch without additional remarks, it is
also possible to use a command like
git send-email --to=bug-gnu-emacs@gnu.org 0001-DESCRIPTION.patch'.
However, we prefer the 'git format-patch' method with attachment, as
doing so delivers patches in the correct and easily-recognizable format
more reliably, and makes the job of applying the patches easier and less
error-prone. It also allows to send patches whose author is someone
other than the email sender.
