This is turning out to be quite a common case to be just
ignoring it and zero filling destination files.
SMB misconfig
NFS with UID mapping errors
file truncation
Windows mandatory locks.
Any others?
If you've a test case, have at it. I'd suggest changing

be transferred" warning at the end and an exit status of 23
so a wrapper script can retry or at least look to see what
the cause was.
