Reproducer: On Windows, Open Idle and editor. In editor grep (alt-f3), for instance, 'print' in /Lib/*.py. While hits are flashing by, close the output window with [x]

2.7.6 or .7: Output window closes, Idle continues as desired.
3.3.5 or 3.4.1: All Idle windows - shell, editor, output
3.4.1+, 3.5.0a, debug builds run from console interpreter:
Output window closes, Idle continues, as desired.
console window displays exception ending with 

  File "F:\Python\dev\5\py35\lib\idlelib\", line 90, in grep_it
    (fn, lineno, line))
  File "F:\Python\dev\5\py35\lib\idlelib\", line 40, in write
    self.text.insert(mark, s, tags)
AttributeError: 'NoneType' object has no attribute 'insert'

The specific fix is to wrap the text insert with try: except: break. The immediate mystery  is why 2.7 did not shutdown with nowhere to print the traceback.

I added try: except: and tested on installed 3.4.1, which previously failed. There is no way that I know of to start repository Idle without a console to print a traceback to. I added a missing import, removed an incorrect comment, added others, and changed 'print x' in 2.7 to 'print(x)' to reduce differences between versions for future patches.
