Subject: [PATCH] [TASK] Adopt the shared .editorconfig

The file is maintained in one place now, the How to Document guide, and
copied out unchanged. This repository's copy pointed at a master in
T3DocTeam that no longer describes what we do.

What changes here: code examples indent two spaces instead of four, so
that a nested example still fits the 80 characters the prose around it
is wrapped to. reST keeps four, because there the indentation is
structure rather than code. The Makefile section covers **.mk as well,
and a .diff is no longer stripped of trailing whitespace, which in a
patch is content rather than whitespace.

Nothing is reformatted by this commit. The file states the rule;
bringing the existing examples in line follows separately.
