From 574f5a59d85153309ea9856f425ca610074e1116 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Tue, 24 May 2016 10:11:05 +0200 Subject: [PATCH] builtin/apply: move 'apply' global into 'struct apply_state' To libify the apply functionality the 'apply' variable should not be static and global to the file. Let's move it into 'struct apply_state'.
