-Conditional -z for old protocols
-
- After we get the @RSYNCD greeting from the server, we know it's
- version but we have not yet sent the command line, so we could just
- remove the -z option if the server is too old.
-
- For ssh invocation it's not so simple, because we actually use the
- command line to start the remote process. However, we only actually
- do compression in token.c, and we could therefore once we discover
- the remote version emit an error if it's too old. I'm not sure if
- that's a good tradeoff or not.
