The --stat of a combined diff is defined as the first-parent stat, going all the way back to 965f803c32 (combine-diff: show diffstat with the first parent., 2006-04-17). Naturally, we gave --numstat the same treatment in 74e2abe5b7 (diff --numstat, 2006-10-12). But --shortstat, which is really just the final line of --stat, does nothing, which produces confusing results: $ git show --oneline --stat eab7584e37 eab7584e37 Merge branch 'en/show-ref-doc-fix' Documentation/git-show-ref.txt | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) $ git show --oneline --shortstat eab7584e37 eab7584e37 Merge branch 'en/show-ref-doc-fix' [nothing! We'd expect to see the "1 file changed..." line] This patch teaches combine-diff to treats the two formats identically.
