From 9f3d54d193d9edcf443c9dd62789af5e8e47635c Mon Sep 17 00:00:00 2001 From: David Aguilar Date: Fri, 15 Jan 2010 14:03:44 -0800 Subject: [PATCH] difftool: Use eval to expand '--extcmd' expressions It was not possible to pass quoted commands to '--extcmd'. By using 'eval' we ensure that expressions with spaces and quotes are supported.
