From 225e115a854036839afa3727c28dcfe46dce4121 Mon Sep 17 00:00:00 2001
From: Joe Atzberger <joe.atzberger@liblime.com>
Date: Wed, 20 Aug 2008 15:40:44 -0500
Subject: [PATCH] issues_stats returns empty results if row/column =
 items.ccode/datetime

Also added ESCAPE="HTML" to column/row headers because users may define
collections that include ampersands, like:
    B&T Rental--Fiction
The Tidy error associated would be:
    line 574 column 29 - Error: general entity "T" not defined and no default entity
