From 0654aa57f30fc7984e19b91cdbee123f929ca7b1 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 13 Mar 2017 21:11:04 +0100 Subject: setup: make read_early_config() reusable The pager configuration needs to be read early, possibly before discovering any .git/ directory. Let's not hide this function in pager.c, but make it available to other callers.
