tests: fixup indexlevel setting in tests

The correct field is underscore-less for consistency with
git-config naming conventions.  While we're at it, beef up
the v2 tests with actual size checks, too.

I also noticed phrase searching still seems to work for
the limited test case, so I left it documented; but the
size checking verifies the space savings.
