Reduce empty space around message list
Review Request #107614 - Created Dec. 6, 2012 and submitted
This patch removes margins around the message list, ensuring the borders of the view are correctly lined-up with other views. When tabs are hidden, it removes the gaps between the view and its surrounding splitters. When tabs are visible, it removes the multiple borders around the message list.
I have been running with it for a few weeks. Works correctly in both wide and normal layouts.
