Notes about the 20160608b-988715a -> 20170228-c325e41585e3 rebase: - refresh commit 519b9751573e against various context changes The CSI Ps ; Ps ; Ps t escape sequence serves for window manipulation. We can use the CSI 8 ; ; t sequence to adapt eg. the xterm window size to the selected console mode.
