Pre commit hook to check git branch prefix to include Jira ticket

commit-msg

#!/usr/bin/env ruby

# Finds the story number from the branch name and injects it
# into the commit message. For instance, if we're on branch
#
# BRAND-1234-Some-Feature
#
# And we had committed with
#
# git commit -m "I did some feature"
#
# Then the final commit message would be
#
# BRAND-1234 I did some feature
#
# If the story number is not present, then the commit will
# be aborted.
