I am not a well experienced rsync user. So it could be that I misunderstood something and this report is wrong. Context: This is about how --old-args and --protected-args are described in the manpage. Problem: It seems to me that the manpage doesn't mention the default value or default behavior. Details: In my understanding that two arguments have an opposite meaning. So they can't be used together. The question about the default values is if I call rsync without any of that arguments how will rsync behave? I assume that `--protect-args` is the default behavior but I'm for away from being sure. If I am not wrong I would suggest to improve the manpage and describe the "default" behavior.
