Many debug logs have no line breaks, so fix them here. - With pull requests: - Open your pull request against `master` - Your pull request should have no more than two commits, if not you should squash them. - It should pass all tests in the available continuous integrations systems such as TravisCI. - You should add/modify tests to cover your proposed code changes. - If your pull request contains a new feature, please document it on the README.
