It would be handy if there was a warning when you attempt to move a file to a "new filename" that is already used in the shared media repository. en.wp now uses parserextensions in the rename request template to warn about such a thing. See url.
It should probably also respect the reupload-shared permission. Or there should be a separate permission for this.
Fixed in r58079.
