Cheating answer:

Hmm, I wonder how the scripted version did that.

$ git grep -Oless -eFast-forward -- contrib/examples/git-merge.sh
        msg="Fast-forward"
        if test -n "$have_message"
        then
                msg="$msg (no commit created; -m option ignored)"
        fi
        new_head=$(git rev-parse --verify "$1^0") &&
        git read-tree -v -m -u --exclude-per-directory=.gitignore $head "$new_head" &&
        finish "$new_head" "$msg" || exit
        dropsave
        exit 0
        ;;
[ok, it's the finish function.  press q to exit the pager, and]
$ git grep -Oless -F -e'finish ()' -- contrib/examples/git-merge.sh
finish () {
        if test '' = "$2"
[...]
                if test "$show_diffstat" = t
                then
                        # We want color (if set), but no pager
                        GIT_PAGER='' git diff --stat --summary -M "$head" "$1"
[...]

So apparently

	git diff --stat --summary -M <before> <after>

will take care of it.

On the other hand, if you want diff output for a single commit (i.e.,
"somewhat like git rev-list --pretty --summary --stat --no-walk but no
commit messages"), then some variation on

	git diff-tree --color --cc --summary --stat --no-commit-id origin/pu

might bring some joy.

Hope that helps,
Jonathan
