Good question. I'm not sure.
There are two other options that I can think of (let's call your
suggestion option 1)):
2) svn could just ignore the no-op move, and do nothing (no warning,
no error, nothing).
3) svn could error out, like it does now, with "Cannot move path
'XXX/todo' into itself"
I think 2) would be more "the Windows way", so if we are aiming for
platform-fidelity here, that would be my choice.
Again, looking at the native "move" command on Windows, we can see
that "move todo todo" acts as if it has done a move, but really didn't
do anything, not even "touch" the file or the parent dir. OTOH, if we
do a real case-only rename, "move todo TODO", the timestamp of the
parent dir is updated (i.e., it really has changed). See below.
