From c795df0dd2176e919dac722dd59d41c25df19b98 Mon Sep 17 00:00:00 2001
From: Filipe David Borba Manana <fdmanana@apache.org>
Date: Sun, 11 Jul 2010 10:50:34 +0000
Subject: Removing unused function couch_util:ascii_lower/1. If ever needed,
 the exact same functionality is provided by string:to_lower/1 (ASCII based,
 not Unicode nor charset based).
