Recommend format-patch and send-email for those who want to submit
patches to this project.

* jc/submitting-patches-mention-send-email:
  SubmittingPatches: encourage users to use format-patch and send-email

In step "(4) Sending your patches", we instruct users to do an
inline patch, avoid breaking whitespaces, avoid attachments, use
[PATCH v2] for second round, etc., all of which format-patch and
send-email combo know how to do well.

The need was identified by, and the text is based on the work by
Cody Taylor.

The Developers Certificate of Origin has a mixture of tabs and white
spaces which is annoying to view if your editor explicitly views white
space characters.

There are general guidelines for writing good tests in t/README
but neither SubmittingPatches nor CodingGuidelines refers to it,
which makes the document easy to be missed.

In an earlier part there is:

  "re-send it with "To:" set to the maintainer [*1*] and "cc:" the list [*2*]"

for the final submission, but later we see

  "Send it to the list and cc the maintainer."

Fix the later one to match the previous.
