From 4c715ebb96acc77008e9cbebc381738611c6006f Mon Sep 17 00:00:00 2001 From: Tanay Abhra Date: Mon, 28 Jul 2014 03:10:39 -0700 Subject: [PATCH] test-config: add tests for the config_set API Expose the `config_set` C API as a set of simple commands in order to facilitate testing. Add tests for the `config_set` API as well as for `git_config_get_*()` family for the usual config files.
