I blogged about tiny refactorings not too long ago. I’ve even added an example showing such a refactoring in my game.
I’m reading Refactoring to Patterns, and figured that the refactorings I’ve mentioned have a name; it’s called the Compose Method. In the book it even has its own chapter (Chapter 7 “Simplification”), where it also refers to other great patterns to help you improve your maintainability of your code.
