Also, fix minor wording mistake in referenced config section.

The basic --local config also doesn't appear to be well defined here.
test-lib.sh sets GIT_TEMPLATE_DIR="$GIT_BUILD_DIR"/templates/blt
If no config template then..? e.g. G-F-W
[core]
	repositoryformatversion = 0
	filemode = false
	bare = false
	logallrefupdates = true
	symlinks = false
	ignorecase = true
