revert: rename original to .orig instead of copying (
issue2282)
By renaming before reverting the content of the file we ensure that we handle
and break hardlinks properly.
Handling of other hardlinks to .orig is somebody elses problem.
inotify: make inotifydirstate.status() returns a tuple of lists.
This makes it consistent with dirstate.status(), which is important if
there are other extensions messing with the output of status(). Those
extensions can safely assume that dirstate.status() returns a tuple of
lists, because its docstring says it does. But
inotifystatus.dirstate() returns a list of lists, which can break
those other extensions.
