Subject: [PATCH v3 2/5] preload-index: use git_env_bool() not getenv() for customization

From: Ben Peart <[email-masked]>
Date: Tue, 18 Sep 2018 23:29:34 +0000

GIT_FORCE_PRELOAD_TEST is only checked for presence by using getenv().
Use git_env_bool() instead so that GIT_FORCE_PRELOAD_TEST=false can
work as expected.
