+ |                              DESCRIPTION                                   |
+ 'svn revert' on a missing versioned directory (yes, a corrupt working copy) 
+ should optionally check out a fresh copy of the dir.  If a versioned directory 
+ has been removed then the meta info is missing and hence there is no 
+ local way to get the dir back.  However, the data is on the server and it 
+ would be nice if svn recognised this and could optionally go to the server 
+ to get the data.  Using the parent's entries file there should be enough 
+ information to get the URL and revision of the missing data.
+ 
+ Note that currently svn just fails silently in this situation.
+ 
+ e.g.
+ 
+ Here we show the current behaviour, and show that the data can be 
+ recovered with a checkout.  It would be cool if the checkout was prompted.
