Those two lines should be removed becuase we can't support all IDEs. You can add those lines into your globla .gitignore.

@IgorDePaula thanks for your work! Could you also look at https://github.com/coduo/php-humanizer/blob/master/spec/Coduo/PHPHumanizer/DateTimeSpec.php#L103 spec and add similar example for Portuguese - Brazil language?

@norzechowicz this file can also be used for Portuguese from Portugal.

@lightglitch Portuguese from Portugal should be stored in file difference.pt.yml - there might be no difference in current translations but we can't exclude such possibility in the future.

@norzechowicz What I'm saying is that you can copy and use this file as difference.pt.yml because now there is no difference. I was thinking that making a pull request with a copy of the file was unnecessary.

PR is more then welcome even if file is just a copy of pt_PT.yml file :) Thanks for reporing that!
