Find all branches that have unmerged commits authored by me. This is my first attempt at a bash script, so if you have suggestions for better/clearer/faster code, please let me know!

myUnmerged.sh

#!/usr/bin/env bash

# usage:
#     local branches only:  `myUnmerged`
#     remote branches only: `myUnmerged -r`
#     all branches:         `myUnmerged -a`
#
# example output:
#
# BRANCH            TOTAL    COMMITS KOGI    KOGI UNMERGED
# feature/branchA     168              50               40
# feature/branchB     169              49               40
# feature/branchC     206              70                0
