This causes problems when using the ssh:// protocol for syncing, and the 
remote side runs monotone < 0.32. In order to solve this temporarily (until 
the other side is updated to 0.32), one can restore the old version of the 
get_netsync_connect_command lua hook that included the branch patterns on the 
mtn commandline to be executed via ssh.

Attached is a lua sniplet made by Ronny (r0nny) Pfannschmidt that overrides 
the get_netsync_connect_command() and use_transport_auth() hooks. By 
introducing an ssh-old:// protocol, it allows connecting to both, sites 
running 0.32, and sites running a version < 0.32. Thanks r0nny for figuring 
out the details!
