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.
