From edf2e37002eeb30a2ccad5db3b3e1fe41cdc7eb0 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 25 Nov 2005 23:14:15 -0800 Subject: git-apply: work from subdirectory. When applying a patch to index file, we need to know where GIT_DIR is; use setup_git_directory() to find it out. This also allows us to work from a subdirectory if we wanted to. When git-apply is run from a subdirectory, it applies the given patch only to the files under the current directory and below.
