From 70bd879ab66aeee809306908e3551d50cdf06802 Mon Sep 17 00:00:00 2001 From: Lars Schneider Date: Fri, 19 Feb 2016 10:16:02 +0100 Subject: config: add '--show-origin' option to print the origin of a config value If config values are queried using 'git config' (e.g. via --get, --get-all, --get-regexp, or --list flag) then it is sometimes hard to find the configuration file where the values were defined. Teach 'git config' the '--show-origin' option to print the source configuration file for every printed value.
