-move versioned package in svn-enabled project. -commit change. -undo movement; ypu are prompted to add to svn - answer yes or no, doesn't matter -redo: the error message 'cannit redo, package already exists' appears, but the exception is thrown also, and after you revert the change you get the 2 entries for the package in tree, and need to clear cashes to continue working with a project. It would be nice to treat attempt to redo more correctly.
