Subject: [PATCH] git-gui: fix use of undeclared variable diff_empty_count

From: Joerg Bornemann <[email-masked]>
Date: Mon, 06 Apr 2009 21:59:28 +0200

Commit 584fa9cc introduced the global variable diff_empty_count, which
is used in diff.tcl. This variable wasn't declared anywhere which
resulted in an ugly error message box instead of the intended
informative message.
