If you've been using cherry_picker.py, please update it ( by doing `git pull` ).

With this update, the branch number is automatically prefixed in the commit message. (https://github.com/python/core-workflow/issues/44)

Added --abort/--continue options to address https://github.com/python/core-workflow/issues/45

Lastly, I added --status option, which will just perform `git status` for the cpython directory.
