Subject: [PATCH 17/24] untracked-cache: temporarily disable with $GIT_DISABLE_UNTRACKED_CACHE

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Sun, 8 Feb 2015 15:55:41 +0700

This can be used to double check if results with untracked cache are
correctly, compared to vanilla version. Untracked cache remains in
index, but not used.
