Under a display-terminal emulator in BUFFER, run PROGRAM on arguments ARGS.
ARGS is a list of argument-strings.  Remaining arguments are WIDTH and HEIGHT.
BUFFER's contents are made an image of the display generated by that program,
and any input typed when BUFFER is the current Emacs buffer is sent to that
program an keyboard input.

Interactively, BUFFER defaults to \"*terminal*\" and PROGRAM and ARGS
are parsed from an input-string using your usual shell.
WIDTH and HEIGHT are determined from the size of the current window
-- WIDTH will be one less than the window's width, HEIGHT will be its height.

To switch buffers and leave the emulator, or to give commands
to the emulator itself (as opposed to the program running under it),
type Control-^.  The following character is an emulator command.
Type Control-^ twice to send it to the subprogram.
This escape character may be changed using the variable `terminal-escape-char'.

`Meta' characters may not currently be sent through the terminal emulator.

Here is a list of some of the variables which control the behaviour
of the emulator -- see their documentation for more information:
terminal-escape-char, terminal-scrolling, terminal-more-processing,
terminal-redisplay-interval.

This function calls the value of terminal-mode-hook if that exists
and is non-nil after the terminal buffer has been set up and the
subprocess started.
