From 872093579a7ca35aa65a89d4050204868b82d5ce Mon Sep 17 00:00:00 2001
From: Eli Zaretskii <eliz@gnu.org>
Date: Sun, 28 Sep 2003 08:24:56 +0000
Subject: [PATCH] (quote_file_name): Print the result instead of returning it. 
 Fix the return type accordingly. (main): Under --eval, don't fail if left
 with additional arguments after decoding options.  Quote file names.
