v1.2 Bump MIN_COMMIT_MSG_LENGTH
In using this commit-msg hook script more, I've found that most common commit messages are about one line of text (120 characters or so) and setting the default MIN_COMMIT_MSG_LENGTH value for the commit-msg-sentiment.py script to 120 results in far fewer false warnings. This value is adjustable via an environment variable. I will document that in the README soon.
