Re: [PATCH/RFC v3] git add -i: Answer questions with a single keypress

["Suraj N. Kurapati" <sunaku@gmail.com>]

Allows the user to answer 'Stage this hunk' questions with a
single keypress, just like in Darcs.  Previously, the user was
forced to press the Return key after every choice they made.
This quickly becomes tiring, burdensome work for the fingers.
