rsync: filter() method + delete=True leads to unexpected results

I'm using an RSync subclass that implements filter() to ignore some parts of a large tree, specifically things where the remote side has a local version like a virtualenv that should not be touched at all, however, it currently always deletes the remote version ...

I'd be happy to improve the code but need to know whether in general filter()=False + delete=True would expect a filtered item to be removed or left alone on the remote side ... my personal favorite would be to have it ignore the deletions on the remote side and eventually adding a delete_filtered option. This would be in sync with the way regular rsync works.

未指定文件或测试。首先定位 RSync filter() 和 delete=True 的处理，然后查看现有的同步测试以及常规 rsync 的文档化行为。当确定了对已过滤远程项的预期处理方式，并由回归测试覆盖时，即视为完成。
