Hi there !
For people who use svnwcrev this patch http://dl.dropbox.com/u/26657232/svnwcrev-2011-05-15.diff bring necessary functionality from SubWCRev. I had a few hours to porting C code from one project to another. Nice to try again KDevelop and C. Was impressed by C APR. I hope that patch will be accepted by Oliver (maintainer of svnvcrev)
