 Start_Search and Search should raise Use_Error if Pattern is malformed, but not

-    AARM Discussion: This cannot be a requirement, since we have to allow
-    Use_Error to be raised (for instance, because the user may not have
-    permission to rename the file, even if New_Name doesn't exist and is a
-    valid name).
+Rename should be supported at least when both New_Name and Old_Name are
+simple names and New_Name does not identify an existing external file.
+
+    AARM Discussion: "Supported" includes raising an exception if either name
+    is malformed, the file to rename doesn't exist, insufficient permission for
+    the operation exists, or similar problems. But this advice requires
+    implementations to document what they do, and tells implementers that
+    simply raising Use_Error isn't acceptable.
