[PATCH 01/34] Documentation/diff-config: fix description of diff.renames

[Junio C Hamano]

From: Matthieu Moy <Matthieu.Moy@imag.fr>

The description was misleading, since "set to any boolean value" include
"set to false", and diff.renames=false does not enable basic detection,
but actually disables it. Also, document that diff.renames only affects
Porcelain.

Sorry, please ignore (I had two similarly named scripts, one drives
git-send-email, the other drives something entirely different, and
mistakenly invoked the former when I meant to run the latter).
