When we compare two non-tracked files, or explicitly specify --no-index, the suggestion to run git-status is not helpful. The patch adds a new diff_options bitfield member, no_index, that is used instead of the special value of -2 of the rev_info field max_count to indicate that the index is not to be used. This makes it possible to pass that flag down to diffcore_skip_stat_unmatch(), which only has one diff_options parameter. This could even become a cleanup if we removed all assignments of max_count to a value of -2 (viz. replacement of a magic value with a self-documenting field name) but I didn't dare to do that so late in the rc game.. The no_index bit, if set, then tells diffcore_skip_stat_unmatch() to not account for any skipped stat-mismatches, which avoids the suggestion to run git-status.
