When I create a revision from Git SVN or SVN project then it uses path relative to the project root (e.g. .arcconfig). Commit attached to this revision uses absolute path (relative to repository root), e.g. tfb/trunk/www/.arcconfig. When I try to arc patch this revision then the path doesn't match.
The same problem probably appears when I try to patch revision in project of SVN repository checked from a different root.
