rsync - Feb 2011 - "extraneous" in commit 3bd9f51917ed5718275c6132006be155239a0550

In this commit you put "extraneous hard-linked files". I find this
confusing because the hard-linked entries may have been created by
rsync itself. I think the previous version is better. Or you could put
"If there are files that are hard-linked at the destination but not at
the origin".
