Subject: [PATCH 2/2] ls: sort files with -l
Date: Thu,  3 Jul 2014 09:40:46 +0200	[thread overview]
Message-ID: <1404373246-10075-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1404373246-10075-1-git-send-email-s.hauer@pengutronix.de>

Always collect directory entries in a string_list and evaluate it
later. This makes sure that the files are printed alphabetically
even when -l is given.
