Summary: Cannot backspace through ">>> " in doc comment

Initial Comment:
IDLEfork 0.9a2, Python 2.2.2, Windows XP



I was documenting another case of Tkinter freeze by 

adding a doc comment in an Editor window when I found 

that the backspace key will not erase a line beginning 

with >>> followed by a space. That is,



"""

Pressed F5 to run

Example window appeared

Clicked button

>>> appeared in Shell window

... more comments

>>> 

...more comments

"""



When I attempted use backspace to delete the ">>> " 

line, the cursor refused to move leftward. Pressing Home 

and hitting the Delete key 4 times works fine.



Two things to think about:

1) The syntax highlighting indicates the cursor is in the 

middle of a comment.

2) This occurred in an Edit window, not a Shell window



FWIW, this defect is hardly worth mentioning. But, if 

IDLE is a tool used by beginners, these odd behaviors 

undermine confidence. When I encountered this defect, 

there was a period of 10 seconds when I thought 

IDLEfork locked up - the backspace key just wasn't 

working.
