It sounds simple to add a diffstat but it's sort of a pain to redo my
workflow...  I don't use git commits.  If I need to make the same change
to multiple files then I end up appending the diff to the end of an
existing email and tweaking the diff hunks together by hand.

I guess I could writing an append_diff.sh script which munges the
diffstat but it seems like it might be error prone.  I'll take a look
though.
