         Adds a separator for spacing groups of tools.
 
-        Note that the meaning of a "separator" is a vertical line under wxMSW and
-        a simple space under wxGTK.
+        Notice that the separator uses the look appropriate for the current
+        platform so it can be a vertical line (MSW, some versions of GTK) or
+        just an empty space or something else.
