bug#17565: 24.3.91; numpad inserts wrong digits

[Josh Tilles <merelyapseudonym@gmail.com>]

When I had first created the ticket, I had only started Emacs with
--no-init-file. However, I just verified that the behavior still shows
up by starting Emacs with -Q.

I'm using a Kinesis Advantage Pro keyboard, and in case you're not
familiar with the model, an image is available here:

I am running Emacs 24.3 and 24.3.91 "side-by-side" by keeping the 24.3
Emacs.app in /Applications but keeping the 24.3.91 Emacs.app in
~/Applications (i.e., /Users/joshua.tilles/Applications/Emacs.app vs
/Applications/Emacs.app)

It might be relevant that I have an unusual keyboard layout: I've done
(most of) the customization using OS X's Keyboard Layouts, not by
using Kinesis's built-in remapping ability. The keyboard customization
file follows, abbreviated to only the relevant portions:
