bisect-builds should print instructions on how to continue bisecting with git

In diagnosing bug 105861, I used bisect-builds for the first time in a long time:

bisect-builds -r 136278:136846 http://www.uofmchildrenshospital.org/Providers/Bio/D_122501
Works: r136298  Fails: r136812
....
Checking revision r136309 (0 builds left to test after this)...
Downloading WebKit-SVN-r136309.dmg to /Users/eseidel/Library/Caches/WebKit-Nightlies/trunk...
######################################################################## 100.0%
Mounting disk image and running WebKit...
Did the bug reproduce in r136309 (yes/no/broken)? yes

Works: r136298  Fails: r136309
http://trac.webkit.org/log/trunk/?rev=136309&stop_rev=136299


That's great, but not close enough, and it should tell me how to continue with git:

           git bisect start [--no-checkout] [<bad> [<good>...]] [--] [<paths>...]

But it would need to lookup the git commits using:
git svn find-rev

(I just learned that Chromium has a bisect-builds.py: http://www.chromium.org/developers/bisect-builds-py  I wonder if it explains how to move to WebKit when the offending revision is a webkit roll. :)
