Bash Pre Commit Hook
# A pre-commit hook that will stash any changes so that we are running our tests
# against what we are committing, not what was on in memory.
# Because I was having trouble getting trap to play nicely with any signal except
# EXIT we just carry around our status and exit with it at the end
