From bb493a5c147a4b60f0f412a71bf9236ede4a560c Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Mon, 8 Aug 2016 23:03:07 +0200 Subject: builtin/apply: move init_apply_state() to apply.c To libify `git apply` functionality we must make init_apply_state() usable outside "builtin/apply.c". Let's do that by moving it into a new "apply.c".
