Do not default to --no-index when given two directories.
git-diff -- a/ b/ always defaulted to --no-index, primarily because the function is_in_index() was implemented quite incorrectly. Noticed by Patrick Maaß and Simon Schubert independently, initial patch was provided by Patrick but I fixed it differently. Signed-off-by: Junio C Hamano <junkio@cox.net>
