svnversion documentation bug in the redbook?

Hi,

http://svnbook.red-bean.com/en/1.7/svn.ref.svnversion.re.html states:

> If invoked on a directory that is not a working copy, svnversion assumes
> it is an exported working copy and prints "exported":
>
> $ svnversion
> exported

However, calling svnversion.exe 1.7.2 (r1207936), installed by the TortoiseSVN 64 Bit installer, outputs the message "Unversioned directory":

> D:\>svnversion
> Unversioned directory

I did not test with older svn versions, as I have no older version available here right now, but this may be either a documentation bug or inaccuracy, or it also might be an incompatible change which is likely to break some scripts relying on the documented behaviour.

Best regards

Markus Schaber
