From 62c64895cfcf3bbf34969a69fa96a631f7d5b14e Mon Sep 17 00:00:00 2001 From: Wincent Colaiuta Date: Thu, 13 Dec 2007 21:24:52 +0100 Subject: "diff --check" should affect exit status "git diff" has a --check option that can be used to check for whitespace problems but it only reported by printing warnings to the console. Now when the --check option is used we give a non-zero exit status, making "git diff --check" nicer to use in scripts and hooks.
