If you don't mind, I'd almost prefer you to do this change separately to make
the test diff simpler and make sure nothing is regressed in the process with
hidden assumption.

You may want to try this:

cd ..
git svn clone svn://svn.chromium.org/chrome -T trunk/tools/depot_tools
depot_tools2
# will take > 5 minutes
cd depot_tools2
svn diff ../depot_tools | patch -p0
git commit -a -m base
git cl issue 6873110
# then use my technique to separate 2 commits as described at
# http://maruel.github.com/landslide/maruel_git.html#slide20

done.
I started differently (no git), so I did it differently. But I bookmarked your
presentation :)
