The above gets the revision using svn itself. But in case svn is not 
installed on that machine (eg if it NFS-mounts a disk from the machine 
used for the svn update)

The above tries to guess revision from existing svn metadata. But in 
case the client used does not leave metadata similar to the Linux 
client, second fallback:
