From 6716027108f426c83038b05baf3f20ceefe6fbd1 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sat, 17 Feb 2007 12:37:25 -0800 Subject: [PATCH] Teach core.autocrlf to 'git apply' This teaches git-apply that the data read from and written to the filesystem might need to get converted to adjust for local line-ending convention.
