Suggestion: Flag modified lines with whitespace-only changes

[Alhadis]

Atom neatly colours lines that've been added, removed or changed since the last commit:

Looking at the classes applied to the line, though, it doesn't seem like there's any way to identify lines that've only been modified with whitespace:

Having a .git-line-whitespace class would be helpful for theme authors wishing to target lines with cosmetic whitespace changes (the way git diff -w would). In my particular case, I wouldn't mind hiding the highlights completely, but as it is, I've no way of doing so with pure CSS.
