First: I already coded a test and am using this patch in git gui and
gitk (there was no way git submodule summary would have worked for
gitk, now it does). Looking really good, will post when this patch
solidifies ...

Actually there are two more and Junio pointed out #7: submodule summary
uses --first-parent and we don't (My testcases don't contain merges, so
i didn't notice).
The difference that is most obvious and was unintended is that the
shortlog is indented by four spaces instead of two. I appended an
interdiff to fix that.
As with the other six, i am not really sure if we should just copy the
behaviour of git submodule summary.

FullAck.
First some examples for the current behaviour (with the patch below
applied):
$ git diff --submodule-summary
Submodule sub 5431f52..3f35670:
> sub3
$ git submodule summary --files
* sub 5431f52...3f35670 (1):
> sub3
$ git diff-index --submodule-summary HEAD -p
Submodule sub 81d7059..3f35670:
> sub3
> sub2
$ git submodule summary
* sub 81d7059...3f35670 (2):
> sub3
> sub2
[$ git diff --cached --submodule-summary HEAD
Submodule sub 81d7059..5431f52:
> sub2
$ git submodule summary --cached
* sub 81d7059...5431f52 (1):
> sub2
$
So the differences are:
1) Dscho replaced the leading '*' with the more explicit "Submodule"
I like the explicit version.
2) submodule summary prints out how many shortlog entries are following
3) submodule summary adds a newline after the shortlog
4) submodule summary uses --first-parent
No idea about the intention here. Lars?
5) submodule summary always prints three '.' between the hashes
Seems like submodule summary didn't do the hassle for performance
reasons. But for consistency i would prefer the new version as we
use it all over the place, no?
6) submodule summary can limit the number of shortlog lines
Hm, i want to see them all. Any users of that -n option?
To take this a bit further: It might be a good idea to let git diff
generate output for submodules that is consistent with that for regular
files. So instead of:
git diff --cached --submodule-summary HEAD -p
Submodule sub 81d7059..5431f52:
> sub2
we could produce:
diff --git a/sub b/sub
index 81d7059..3f35670 160000
--- a/sub
+++ b/sub

(This is the output of a git diff without the --submodule-summary option
with an appended shortlog)
I like the second variant (mainly because of consistency). Opinions?
And here the promised indentation depth fix interdiff:
