    filediff: Don't disable updating when syncpoints aren't yet active
    
    This is a problem if, for example, the user sets a syncpoint in the
    left pane without setting one in the right pane. We need matching
    syncpoints in each pane to do the syncing so don't actually sync and
    don't show our warning, but we do disable comparison updating.
    
    This patch changes this so that we only disable comparison updating
    if the actual differ has a list of syncpoints that it's using.
