I don't think you really answer the question. When there is an
addition, svn does show the addition. Now, the rename is just a
copy + a delete. The delete is shown as expected. When there is a
copy, svn shows the diff against the old version; when there are
no diffs (i.e. one just has a copy, not a copy + modifications),
svn doesn't show anything. I wonder if svn shouldn't output:

Index: newname.txt (copied)
===================================================================

like it does for deleted files, or even:

Index: newname.txt (copied from oldname.txt)
===================================================================
