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.
