Sure, I'll try to remember to add them. I do my work in a git repo and
then do:

git diff > mypatch.patch
quilt import mypatch.patch
patch -p1 -R < mypatch.patch
rm mypatch.patch

and then I pull patches/mypatch.patch into my email to do the RFC.

diffstat patches/mypatch.patch should also give the same. Hmm, I wonder
if quilt has any commands to do this for me?

Thanks,
