 reject your attempts at fine-grained control (if one or more flags needed
 to be send to the server and the server was too old to understand them).
 
+dit(bf(--msgs2stderr)) This option changes rsync to send all its output
+directly to stderr rather than to send messages to the client side via the
+protocol (which normally outputs info messages via stdout).  This is mainly
+intended for debugging in order to avoid changing the data sent via the
+protocol, since the extra protocol data can change what is being tested.
+Keep in mind that a daemon connection does not have a stderr channel to send
+messages back to the client side, so if you are doing any daemon-transfer
+debugging using this option, you should start up a daemon using bf(--no-detach)
+so that you can see the stderr output on the daemon side.

 dit(bf(-q, --quiet)) This option decreases the amount of information you
 are given during the transfer, notably suppressing information messages
 from the remote server. This option name is useful when invoking rsync from
