Terminal Management
-------------------

 - Function: void rl_prep_terminal (int meta_flag)
     Modify the terminal settings for Readline's use, so `readline()'
     can read a single character at a time from the keyboard.  The
     META_FLAG argument should be non-zero if Readline should read
     eight-bit input.

 - Function: void rl_deprep_terminal (void)
     Undo the effects of `rl_prep_terminal()', leaving the terminal in
     the state in which it was before the most recent call to
     `rl_prep_terminal()'.

 - Function: void rl_tty_set_default_bindings (Keymap kmap)
     Read the operating system's terminal editing characters (as would
     be displayed by `stty') to their Readline equivalents.  The
     bindings are performed in KMAP.

 - Function: int rl_reset_terminal (const char *terminal_name)
     Reinitialize Readline's idea of the terminal settings using
     TERMINAL_NAME as the terminal type (e.g., `vt100').  If
     TERMINAL_NAME is `NULL', the value of the `TERM' environment
     variable is used.
