Patch: more detailed error logging when an ACL unpack error occurs

[Ryan Schmidt]

Hi, I maintain the rsync port in MacPorts.

For ten years, we've been carrying around a one-line patch which was described by its contributor this way:

> Occasionally, sync will report an ACL unpack error, but the user will be left in the dark regarding which file(s) was affected. This adds more detailed error logging


https://trac.macports.org/ticket/36169

I don't know if the contributor ever attempted to contribute it to the rsync project or only sent it to us at MacPorts.

Would you be interested in adding this patch to the rsync-patches repo or incorporating it into rsync directly?
