Implement a way to ignore read permission errors, similar to "--ignore-missing-args"

[Romain-Geissler-1A]

Hi,

Would it be possible to implement a new flag (or update the behavior of "--ignore-missing-args" so that what can be omitted is not only missing source files, but also source files that do exist, but that you cannot read ? I am in a situation where I have a list of remote files I try to download, but among this list I have things like /run/nscd/passwd that is not world-readable, and which actually I accept to not rsync. However I don't know in advance which file will be readable and which won't, I wish rsync could work in "best-effort" mode even with permission errors, and not log any error when this happens.

Cheers, Romain
