Won't work for me. The reverse part would be way larger than the to-commit part.

Hmm.. interesting. Never got around to actually use magit. I may have
a good reason now.

Hmm..yeah something like grep for chunks, then automatically splitting
those chunks out would be nice.

I have another use for such a tool too. When .po files are
automatically updated by intltool (gnome translation helper tool),
comment lines are all changed because they contain source line and
those line likely change. With this tool I can filter out comment-only
changes.

Thanks for the idea.
