Thanks!  After some brief testing this is in now my tree on repo.or.cz.

I wouldn't say illiterate, given this contribution.  :)

Yea, I see why you are doing a do_rescan at the end.  I was going
to suggest just calling reshow_diff but that doesn't get the lists
updated properly when a file is being initially staged as a result
of the current line being added.

Editing the Tk widget is possible, but it can be a pain.

Yup.  Tk text widgets have an extra "\n" at the end of the content
that was inserted into it.  Thus an empty text widget has a single
LF as its content.  Weird, I know.
