#patches(from, to, paths: [], exclude_paths: [], **kwargs) ⇒ Object

FIXME: Убрать логику исключения путей exclude_paths из данного класса, FIXME: т.к. большинство методов не поддерживают инвариант FIXME “всегда выдавать данные с исключенными путями”. FIXME: Например, метод diff выдает данные без учета exclude_paths. FIXME: Лучше перенести фильтрацию в GitArtifact::diff_patches. FIXME: ИЛИ обеспечить этот инвариант, но это ограничит в возможностях FIXME: использование Rugged извне этого класса и это более сложный путь. FIXME: Лучше сейчас убрать фильтрацию, а добавить ее когда наберется достаточно FIXME: примеров использования.
