From 638fa623d5b5fb392a062edf61ccf086d35ab26b Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 24 Feb 2016 13:48:11 +0100 Subject: [PATCH] git config: report when trying to modify a non-existing repo config It is a pilot error to call `git config section.key value` outside of any Git worktree. The message error: could not lock config file .git/config: No such file or directory is not very helpful in that situation, though. Let's print a helpful message instead.
