From 61ed71dcff8448b0700ef032aa1f962649306624 Mon Sep 17 00:00:00 2001 From: David Aguilar Date: Sat, 9 Jan 2010 20:02:41 -0800 Subject: [PATCH] difftool--helper: Remove use of the GIT_MERGE_TOOL variable An undocumented mis-feature in git-difftool is that it allows you to specify a default difftool by setting GIT_MERGE_TOOL. This behavior was never documented and was included as an oversight back when git-difftool was maintained outside of git. git-mergetool never honored GIT_MERGE_TOOL so neither should git-difftool.
