Junio C Hamano 5c21ac0e7c Libified diff-index: backward compatibility fix.
"diff-index -m" does not mean "do not ignore merges", but means
"pretend missing files match the index".

The previous round tried to address this, but failed because
setup_revisions() ate "-m" flag before the caller had a chance
to intervene.
