Subject: [PATCH 2/2] Teach git-add--interactive to highlight untracked file prefixes

From: Wincent Colaiuta <[email-masked]>
Date: Sat, 1 Dec 2007 15:07:20 +0100

Tweak the list_and_choose function so that untracked files will
use the automatic prefix detection machinery.

This works because while previously we handled arrays (command
menus), hashes (patch subcommand) now we explicitly handle strings
(add untracked subcommand).
