+
+ Terminal scrollback with ring buffer
+
+ This patch adds a ring buffer for scrollback to the terminal. The
+ advantage of using a ring buffer is that the common case, scrolling with
+ no static screen content, can be achieved very efficiently by
+ incrementing and decrementing the starting line (modulo buffer size).
+
+ The scrollback buffer is limited to HISTSIZE lines in order to bound
+ memory usage. As the lines are allocated on demand, it is possible to
+ implement unlimited scrollback with few changes. If the terminal is
+ reset, the scroll back buffer is reset, too.
