Try importing readline

[asmeurer]

Compare the following two Python scripts (Python 3)

input()

import readline
input()

For each, try typing something and then arrowing left. With the first, it just types ^[[D. With the second, it arrows left. It also supports all the standard things like emacs keybindings and even history.

Nikola should try importing readline for any command that takes user input (such as new_post). I believe it has to be done with try, except because readline is not available on all platforms.
