From 7010a6c924ce6937c8e040c837a118663d6dfdb3 Mon Sep 17 00:00:00 2001
From: Thomas Jaeger <ThJaeger@gmail.com>
Date: Wed, 7 Oct 2009 13:05:15 -0400
Subject: Rework 'xinput list' code

* Drop the questionable --loop option
* Add a --long option (opposite of --short)
* Make --short the default if no device argument is given
* XI2: Make it possible to query a single device

Signed-off-by: Thomas Jaeger <ThJaeger@gmail.com>

squashed in a man page update for --short and --long.
