I have had this in my ~/.gitconfig for a long time.

[alias]
	wsadd = "!sh -c 'git diff -- \"$@\" | git apply --cached --whitespace=fix;\
		git co -- ${1-.} \"$@\"' -"

That is, "take what's different from the _index_ and the working tree, apply that difference while correcting whitespace errors to the index, and check the result out to the working tree". This would _not_ touch existing whitespace-damaged lines that you are not touching, and honours the customized definition of what is considered whitespace breakage for each paths (which you set up with the attributes system).
