FIX: Issue #3

Maybe squash some/all of the commits, we don't necessarily need all that blow-by-blow history? Although we've never been fussy about this before...

I think that some granularity in commits makes patches a lot easier to understand (and to review) and simplifies a lot when using git bisect to find regression bugs, that's why I usually make small commits...
Also by using feature branches, when you see the history, even if it branches have a larger number of commits, you can clearly see that these commits are related.
Anyway you are probably right that 6 commits were too many I squashed some of them, does it look better now?
