I think that depends on the definition of "strip it off" ;-)  What I
meant was that whitespace coloring can appear anywhere on the line,
e.g.

    echo COPYING whitespace=tab-in-indent,-space-before-tab >.gitattributes
    printf " \tHeh\n" >>COPYING
    git diff

will give you

    <new> + <reset> SP <wserror> HT <reset> <new> Heh <reset> LF

Obviously, stripping "+" painted in "new" is not sufficient.

	Side note: hmm, shouldn't that SP painted in <new>, though?

Yes, I agree with that 100%.
