 2.4.10 Utility Functions
 ------------------------
 
  -- Function: void rl_replace_line (const char *text, int clear_undo)
      Replace the contents of `rl_line_buffer' with TEXT.  The point and
      mark are preserved, if possible.  If CLEAR_UNDO is non-zero, the
      undo list associated with the current line is cleared.
 
  -- Function: int rl_extend_line_buffer (int len)
      Ensure that `rl_line_buffer' has enough space to hold LEN
      characters, possibly reallocating it if necessary.
 
  -- Function: int rl_initialize (void)
      Initialize or re-initialize Readline's internal state.  It's not
      strictly necessary to call this; `readline()' calls it before
      reading any input.
 
  -- Function: int rl_ding (void)
      Ring the terminal bell, obeying the setting of `bell-style'.
 
  -- Function: int rl_alphabetic (int c)
      Return 1 if C is an alphabetic character.
 
  -- Function: void rl_display_match_list (char **matches, int len, int
           max)
      A convenience function for displaying a list of strings in
      columnar format on Readline's output stream.  `matches' is the list
      of strings, in argv format, such as a list of completion matches.
      `len' is the number of strings in `matches', and `max' is the
      length of the longest string in `matches'.  This function uses the
      setting of `print-completions-horizontally' to select how the
      matches are displayed ( Readline Init File Syntax).
 
    The following are implemented as macros, defined in `chardefs.h'.
 Applications should refrain from using them.
 
  -- Function: int _rl_uppercase_p (int c)
      Return 1 if C is an uppercase alphabetic character.
 
  -- Function: int _rl_lowercase_p (int c)
      Return 1 if C is a lowercase alphabetic character.
 
  -- Function: int _rl_digit_p (int c)
      Return 1 if C is a numeric character.
 
  -- Function: int _rl_to_upper (int c)
      If C is a lowercase alphabetic character, return the corresponding
      uppercase character.
 
  -- Function: int _rl_to_lower (int c)
      If C is an uppercase alphabetic character, return the corresponding
      lowercase character.
 
  -- Function: int _rl_digit_value (int c)
      If C is a number, return the value it represents.
