Thomas Guyot-Sionnest ff0c7fa8cb diff: fix modified lines stats with --stat and --numstat
Only skip diffstats when both oids are valid and identical. This check
was causing both false-positives (files included in diffstats with no
actual changes (0 lines modified) and false-negatives (showing 0 lines
modified in stats when files had actually changed).

Also replaced same_contents with may_differ to avoid confusion.
