From 4a689afb030c1cd5aa1c141db94bbf9dde42f05e Mon Sep 17 00:00:00 2001 From: Michael J Gruber Date: Tue, 14 Dec 2010 10:18:35 +0100 Subject: difftool: provide basename to external tools Currently, only configured diff helpers get the basename of the file being compared. Tools specified with "git difftool -x" only get the names of temporary files for the different versions. Export BASE so that an external tool can read the name from the environment. Rather than using a third argument, this avoids breaking existing scripts which may somewhat carelessly be using "$@" rather than "$1" "$2".
