I know it's useless data now, but I'm sure this won't be the last time you put sensitive data in a git repo... I know it happens to me often :D
This is why I always make config files for my projects that contain usernames and passwords, add that config to the .gitignore and then create a sample_config with the blank version. I learned to do this after one or two commits containing sensitive data. =)
That's something useful that will also keep us from being lazy and hardcoding things when we usually need a config anyway :D
