Usage: dht mass-change [-n] [MESSAGE] [ACTION] DIRECTORY ...
This script runs ACTION in each of the given directories. If the ACTION
effected a change, it will add MESSAGE to the changelog.
It assumes that all directories are in the same git repository as this script.
It ensures that the repository is clean to begin with, and will commit all
changes at once at the end, if there was a change.
