From 418566b6fdcc0eb1b5549d0742366aa13a7ff277 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 29 Jan 2009 17:30:51 +0100 Subject: [PATCH] Fix 'git diff --no-index' with a non-existing symlink target When trying to find out mode changes, we should not access the symlink targets using stat(); instead we use lstat() so that the diff does not fail trying to find a non-existing symlink target.
