The unicode 'bar' icon causes a SyntaxError when using Ruby 1.9.3 p327.

Adding # encoding: utf-8 fixes the error. Really not enough for a pull request, though.

Otherwise, works really well!

Adding the following at the top of source.rb fixes it for me

#!/bin/env ruby

encoding: utf-8

If a user has changed their username at some point in git config, then they will show up as two people.

Consider using email address (%ae) instead, and maybe picking the last username that is used with that email.

For example: git log --pretty=format:'%ae;%an'

Just because I looked at that and went "omg, that's cool" and I'm betting other people did as well, so a one line note pointing at the creation software would be a really nice thing to have.
