Ok, we've figured out the reason for this.

As an aside, backupdir was designed to work from one level further up
the directory tree.  If you run
	backupdir ~/ender2/work/
it will create a diff and revision files for each workspace, rather
than for each directory in a single workspace.

I have a backup directory on a backed up file system, which has a
sub-directory for each machine, and that subdirectory is full of
symlinks to all my workspaces on that machine.  So cron runs a backup
on each machine directory

e.g.	backup
		ender 
			ws1 
			ws2
		hydra
			ws1
