Rsync 3.1.0dev supports the %C escape in log formats, which can output
the sender's checksum anytime a file is transferred (even without -c),
or for any file when -c is used.  Example options for controlling the
output format:

    --out-format='%C %n%L'
    -ii --out-format='%i %C %n%L'

There is also a log-checksum.diff in the patches directory for the 3.0.x
