Dscho condensed his initial patch with the interdiff you mentioned,
additionally silenced a compiler warning and activated --first-parent.
This follows as patch 1/4. Patches 2/4 to 4/4 contain my two bugfixes
and the testcase i copied from submodule summary while adapting it to
the changes of the output format.

The remaining differences from the output shown by submodule summary are:

1) git diff shows only two dots for a fast forward (submodule summary
   always shows three)
2) git diff shows "Submodule" instead of a single '*' in the first line
3) git diff doesn't add a newline after each shortlog
4) submodule summary prints out the number of shortlog entries, this
   version does not
5) submodule summary can limit the number of shortlog lines, git diff
   can't do that right now
6) When files are replaced by a submodules or vice versa, git diff
   generates an extra hunk for the deleted/added file and one saying
   "(new submodule)"/"(submodule deleted)"

Will do when it is clear which of the 6 differences should be fixed and
which can stay.
