[PATCH] vcs_info svn: Recognize working copies in need of an upgrade.

[Daniel Shahaf <d.s@xxxxxxxxxxxxxxxxxx>]

---
To test this:

% svnadmin create r
% svn co -q file://$PWD/r wc
% cd wc 
% rm -f .svn/wc.wb
% echo 9 >! .svn/format >! .svn/entries
% 

I wonder if more errors should be handled.

Cheers,

Daniel
