[PATCH 2/2] completion: use new 'git config' options to reliably list variable names

["SZEDER Gábor" <szeder@ira.uka.de>]

List all set config variable names with 'git config --list-names' instead
of '--list' post processing.  Similarly, use 'git config
--get-name-regexp' instead of '--get-regexp' to get config variables in a
given section.
