From e612eb6ba227104761b9c6fafe375c74267bba09 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Sun, 13 Dec 2009 23:12:44 -0600 Subject: Remove trailing whitespace on all lines in list_display This ensures we never have trailing whitespace. Take the following text, with line numbers added for clarity: 1. Title : item1 item2 item3 item4 2. item5 item6 item7 item8 3. item9 itemA itemB itemC Laszlo Papp helpfully pointed out we would have two trailing spaces on line three after the last item. However, we also had these trailing spaces on lines one and two, which the initial patch didn't take care of. This can be seen on something like `pacman -Qi glibc`.
