I am puzzled at the differences between the 2.7 and 3.4 patches. There are only three differences between the files

- from Tkinter import Tk, Text, TclError
+ from tkinter import Tk, Text, TclError
?      ^
- from test.test_support import requires
+ from test.support import requires
?           ^
-     get_selection_indices = EditorWindow.get_selection_indices.im_func
+     get_selection_indices = EditorWindow. get_selection_indices
 
and none of these should affect the patch.

The attached patch adds a limit parameter to the FormatParagraph.format_paragraph_event method ReformatParagraph.py that is called as self.formatter in the tests.
  cls.formatter = fp.FormatParagraph(editor).format_paragraph_event
With this change, we can augment the calls to
        self.formatter('ParameterDoesNothing', 72)
and the tests will ignore the configured value.
