We meant that the default behavior of `--quote-email` (i.e. without
--compose enabled) will open the editor with the given patches in
argument and will quote the message body in the first one.

Actually the Control-C during the edition will cancel all the
annotations written (including the cited email).

It's already what we did: the first original patch is copied in a
temporary file. However, if the edition went well (i.e. the editor
closed by the user), the temporary file will erase the original one.

Yes, I completely agree this suggestion.

Thank you for the advice, I'll keep it in mind.

Sorry, I copied the previous error messages.

Yes, indeed. I'll add these tests in the next version.
Thank you for the review.
