1.17 was the last version that met the basic criteria of helping first time developers sucessfully make their first commit. That's the most important task of git-review. Revert all changes since that version. Unfortunately, some of the minor bug fixes since then will have to be re-written because 1.18, in addition to introducing basic bugs, also introduced significant code reorganization. Addresses bug 1038269. Re-fixed pep8 errors since we've become more strict since 1.17. Change-Id: Ia3495a6bb883ddf08155c6bfb69a58d19a15a804
