This is not "do this in emacs", but here is a possible approach.
You can ask "git diff" about what you changed, and actually apply
the change while fixing whitespace errors. I.e.
git diff sha1_file.c | git apply --cached --whitespace=fix
git diff
git checkout sha1_file.c
The first step will add a cleaned-up version to your index.
The second "diff" (optional) is to see what whitespace errors are
introduced when going from that cleaned-up version to what you have
in the working tree.
With the last step you would update the working tree version to the
cleaned-up version from the index.

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