Subject: [PATCH 2/3] completion: add find_argument_and_value() function

From: Stephen Boyd <[email-masked]>
Date: Wed, 6 May 2009 23:15:05 -0700

Add a function to get arguments and their associated value. This is used
by the config completion to find config file arguments.

I'm not sure if this is correct. It works for the case I have, but
others I'm not so sure. Let's just say I'm no bash expert.
