It sends most keyboard input characters to the program, and displays
output from the program in the buffer. This is similar to the
traditional comint mode, and modes derived from it (such as shell and

The sub-buffer is defined in terms of three buffer-local-variable:

The height of the sub-buffer, in screen lines.
