Thanks for the review Philip.

Yes, exactly.

Yes should be, Will update my patch to handle this.

I tested this

$svn co http://localhost/svn <-- Repo itself instead of parent of repositories.
$cd svn
$svn ps 'a' 'b' .
$svn ci -m "commit" <-This worked as per the authz rules. Anyway will do the directory/file creations to check in case!.

Let me see and do if needed.

Will update the comment.
