From 61af494ca4e63cdc484ea091617ab5f3974f2f9c Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 26 Nov 2008 09:58:41 -0800 Subject: [PATCH] Teach "git diff" to honour --[no-]ext-diff MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The original intention of 72909be (Add diff-option --ext-diff, 2007-06-30) was to optionally allow the use of external diff viewer in "git log" family (while keeping them disabled by default). It exposed the "allow external diff" bit to the UI, but forgot to adjust the "git diff" codepath that was set up to always allow use of the external diff viewer. Noticed by Nazri Ramliy; tests by René Scharfe squashed in.
