App does not capture KP_Enter.

Describe the bug

App does not capture KP_Enter.

To Reproduce

The app captures the keyboards Return, but not keypads return/enter.
xev outputs keyboard enter as Return, and keypad enter as KP_Enter.

Expected behavior

I would expect KP_Enter to be bound in the same way Return is.

Environment

Episilon (and omega for that matter) -git master
Arch Linux Xorg.
