From b575b2f1f420bf82557beab0f4ec12e5aa832bea Mon Sep 17 00:00:00 2001 From: Pat Thoyts Date: Wed, 15 Apr 2009 16:54:19 +0100 Subject: [PATCH] gitk: Handle external diff tool with spaces in the path This fixes the launching of external diff to handle a diff tool that has spaces in the path. This ensures a correctly formed tcl list is passed to the open command with a single pipe character prefixing the list (as per the tcl manual page for open). The specific fault observed was that selecting WinMerge as the diff tool from the default installed location in Program Files failed to be launched from the context menu.
