From 9b96f7cb7a37e00044b068cbeb3027d559a4d9f7 Mon Sep 17 00:00:00 2001
From: Immae <immae@immae.eu>
Date: Mon, 16 Jun 2014 22:05:26 +0200
Subject: - Added possibility to mark a line in red, using escape sequence `a
 la xterm` - Possibility to force redraw of "oneshot" processes - Bug
 correction: when the window size is too small (< 3), we asked for a  
 negative amount of lines from the buffer
