[PATCH] completion: Replace config --list with --get-regexp

[Todd Zullinger <tmz@pobox.com>]

James Bardin noted that the completion spewed warnings when no git
config file is present.  This is likely a bug to be fixed in git config,
but it's also a good excuse to simplify the completion code by using the
--get-regexp option as Jeff King pointed out.

Something like this perhaps?  Perhaps the commit message could use
adjustment to reference your fix for 'config --list'?
