Couldn't you just do
git checkout -- .
after staging your approved changes?
To selectively zap uncommitted changes from your working tree, you could
do
git checkout --patch -- .
I'm not sure overloading `git add` with a "reverse" action is a good
idea. I'm actually prefer pragmatism over conceptual purity but I'm
not sure the prospective gain here is clear.
