Hm, while this issue could certainly be addressed as part of issue #898, it doesn't have to. I.e., I don't fully agree that this is part of that issue.

I can perfectly imagine the following happening, after issue #898 would be resolved (let's imagine, in the post-#898-era, moves are shown as modifications on the parent dir(s) with an additional note about the move):

--------
$ svn mv test.txt test.txt2
M . (moved test.txt to test.txt2)

$ svn status -N
M . (moved test.txt to test.txt2)

$ svn mv test.txt2 test.txt
M . (moved test.txt2 to test.txt)

$ svn status -N
R test.txt
--------

For this last status, I would expect either:
- SVN understands that this is a no-op, and just doesn't show it anymore as a local modification.
- SVN shows both moves, and also applies them on the server when committing:
$ svn status -N
M . (moved test.txt to test.txt2)
M . (moved test.txt2 to test.txt)

Besides, I don't think you need #898 to be solved to solve this issue. OTOH, if issue #898 is more likely to get addressed (in 1.8 let's hope), and this would be solved as a part of it, I would also be happy :).

If this is not logged as a new issue, then maybe we should at least at a note about this to #898, so that this is not overlooked.
