That is, it will tell Unison not just what files are changing right now, but what files have changed since the last time we ran Unison with "-repeat watch" for these replicas.

Ok I just got built on my windows machine in cygwin and one of my ubuntu 
machines.  Can you tell me how I start up the new filewatcher functionality?
