Quick glance in to the state of your git branches
#!/usr/bin/env python
"""
This script implements a git subcommand for viewing git branches with
a summary on how far behind/ahead each branch is compared to current branch.
copy the file to somewhere in the path as git-branches and make it executable
then you can use `git branches` to see summary of unmerged branches
`git brnaches -a` will give a summary of all branches
This is mostly a python port of similar ruby script by @sosedoff
