gitk: Show changes in index and changes in working directory separately
This makes gitk show up to two fake commits when there are local changes in the repository; one to represent the state of the index and one to represent the state of the working directory. The commit representing the working directory is colored red as before; the commit representing the index state is colored magenta (as being between red and blue in some sense). Signed-off-by: Paul Mackerras <paulus@samba.org>
