@tarruda I don't agree. Surely changes to the style add some noise to the PR, but I am very bad in guessing what an abbreviation stands for which makes it hard to review the code. These changes are of the type one would like to postpone forever but it has to be done. If the style changes should go in a seperate PR, a style-PR beforehand is the way to go.
I think, we should definitely stick stricter to the style guide.
