[Oberon] Revision numbers in A2 repository.

[peter at easthope.ca]

When "svn update source" finishes it reports "Updated to revision 5906."

Whereas https://trac.inf.ethz.ch/trac/lecturers/a2/browser/trunk shows 
    source                                             6090
    
 I've read 
 http://svnbook.red-bean.com/en/1.7/svn.basic.in-action.html#svn.basic.in-action.revs
and still don't recognize why there are two different revision numbers.  A hint will be 
appreciated.  Thanks,                                    ... Peter E.
