git-config: better document default behavior for `--include`

As described in the commit message of 9b25a0b (config: add include directive, 2012-02-06), the `--include` option is only on by default in some cases. But our documentation described it as just "defaults to on", which doesn't tell the whole story. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
