prompts: bugfix: prompt_for_input breaking input

[yanivhasbani]

prompt_for_input breaks long input strings incorrectly due to a bug in python's input functions.

E.G:

from humanfriendly.prompts import prompt_for_input, prompt_for_choice

x = [
'/System/Library/CoreServices/SpringBoard.app/SpringBoard', 
'/System/Library/PrivateFrameworks/SpringBoard.framework/SpringBoard', 
'/System/Library/PrivateFrameworks/SpringBoardHome.framework/SpringBoardHome', 
'/System/Library/PrivateFrameworks/SpringBoardFoundation.framework/SpringBoardFoundation', 
'/System/Library/PrivateFrameworks/SpringBoardUIServices.framework/SpringBoardUIServices', 
'/System/Library/PrivateFrameworks/SpringBoardServices.framework/SpringBoardServices', 
'/System/Library/PrivateFrameworks/SpringBoardUI.framework/SpringBoardUI', 
'/System/Library/PrivateFrameworks/AXSpringBoardServerInstance.framework/AXSpringBoardServerInstance', 
'/System/Library/SpringBoardPlugins/StoreDemoPlugin.servicebundle/StoreDemoPlugin'
]

prompt_for_choice(x)

Expected result:

1. /System/Library/CoreServices/SpringBoard.app/SpringBoard
2. /System/Library/PrivateFrameworks/SpringBoard.framework/SpringBoard
3. /System/Library/PrivateFrameworks/SpringBoardHome.framework/SpringBoardHome
4. /System/Library/PrivateFrameworks/SpringBoardFoundation.framework/SpringBoardFoundation
5. /System/Library/PrivateFrameworks/SpringBoardUIServices.framework/SpringBoardUIServices
6. /System/Library/PrivateFrameworks/SpringBoardServices.framework/SpringBoardServices
7. /System/Library/PrivateFrameworks/SpringBoardUI.framework/SpringBoardUI
8. /System/Library/PrivateFrameworks/AXSpringBoardServerInstance.framework/AXSpringBoardServerInstance
9. /System/Library/SpringBoardPlugins/StoreDemoPlugin.servicebundle/StoreDemoPlugin

Enter your choice as a number or unique substring (Control-C aborts):

actual result:

1. /System/Library/CoreServices/SpringBoard.app/SpringBoard
2. /System/Library/PrivateFrameworks/SpringBoard.framework/SpringBoard
3. /System/Library/PrivateFrameworks/SpringBoardHome.framework/SpringBoardHome
pringBoardFoundation.framework/SpringBoardFoundation
5. /System/Library/PrivateFrameworks/SpringBoardUIServices.framework/SpringBoardUIServices
6. /System/Library/PrivateFrameworks/SpringBoardServices.framework/SpringBoardServices
/PrivateFrameworks/SpringBoardUI.framework/SpringBoardUI
8. /System/Library/PrivateFrameworks/AXSpringBoardServerInstance.framework/AXSpringBoardServerInstance
9. /System/Library/SpringBoardPlugins/StoreDemoPlugin.servicebundle/StoreDemoPlugin

your choice as a number or unique substring (Control-C aborts):
