[issue14254] IDLE - shell restart during readline does not reset readline

[Roger Serwy]

New submission from Roger Serwy <roger.serwy at gmail.com>:

In PyShell.py, the "readline" method enters a nested event loop for handling input. 

If the shell is restarted, the nested event loop remains until after the first press of "enter" causes the "enter_callback" to quit the nested event loop. The effect is that the first line of input to the prompt is ignored by the new shell.

Attached is a patch against 3.3 to fix the problem.
