alternate approach for supporting svn schemes for repository paths We now intercept the operations in the local repo class, and handle the relevant operation ourselves. This frees us from wrapping all relevant commands and replicating their functionality. The implementation is incomplete; only one test has been modified to use the standard Mercurial API with the changed URLs. Once changed, those tests will likely reveal bugs or missing features in the new wrappers. Also, new wrappers will be needed for handling conversion flags such as -A/--authormap.
