  A new column, local_relpath_fs, is added that contains the path as stored in the file system. This column will be used on all systems to interact with the file system. Currently, the content of columns local_relpath and  local_relpath_fs will be identical on all file systems except HFS+.
  
+ {{{#!wiki comment
+ can we use a term (eg, "disk path") that avoids confusion with fs == libsvn_fs?

  All commands that access files in the Working Copy must do so by getting the path from the column local_relpath/local_relpath_fs. 
  
- TODO: Investigate which subcommands currently use local_relpath for other purposes than accessing the file. With alternative 1 (abover), it will NOT be acceptable to use local_relpath for comparison/substring operations with other paths, e.g. repos_path.
