(svn r14897) -Codechange: don't allow a few command flags to be sent over the network as it's bogus information anyway; e.g. the "do not send over network" flag as it will be set whenever the command is received from the server/client.

-Codechange: test earlier whether the command (send from the server) is actually valid.
