prepare-commit-msg git hook to automatically prepend on to the commit message. I think this was born from here: https://medium.com/@nicklee1/prepending-your-git-commit-messages-with-user-story-ids-3bfea00eab5a

# Include any branches for which you wish to disable this script
if [ -z "$BRANCHES_TO_SKIP" ]; then
  BRANCHES_TO_SKIP=(master main develop test)

# Get the current branch name and check if it is excluded
BRANCH_NAME=$(git symbolic-ref --short HEAD)
BRANCH_NAME="${BRANCH_NAME##*/}"
BRANCH_EXCLUDED=$(printf "%s\n" "${BRANCHES_TO_SKIP[@]}" | grep -c "^$BRANCH_NAME$")
BRANCH_IN_COMMIT=$(grep -c "$BRANCH_NAME\:" $1)

# If it isn't excluded, prepend the trimmed branch identifier to the given message
if [ -n "$BRANCH_NAME" ] && ! [[ $BRANCH_EXCLUDED -eq 1 ]] && ! [[ $BRANCH_IN_COMMIT -ge 1 ]]; then 
  sed -i.bak -e "1s/^/$BRANCH_NAME\: /" $1
