From d7ac12b25d375d32372b13f74e90425ca21d5dc1 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 1 Aug 2007 01:29:38 +0100 Subject: [PATCH] Add set_git_dir() function With the function set_git_dir() you can reset the path that will be used for git_path(), git_dir() and friends. The responsibility to close files and throw away information from the old git_dir lies with the caller.
