While I was checking out the svn, it failed in the middle with the message:
svn: In directory 'wv\examples'
svn: Error processing command 'readonly' in 'wv\examples'
svn: Can't set file 'wv\examples\.svn\text-base\this-file-crashes-msword.doc.svn
-base' read-only: The system cannot find the file specified.
No ideas yet...
Later just used "svn export" for each file that yet to be downloaded, and downloaded them one by one, and got all those missing files!
